Secheron Plasmafix 50-S Plasma\TIG Welder

[jptech]

Hi all..., I just bought a Plasmafix 50-S Plasma\TIG Welder, and I'm trying to find an owner's manual for it. I've been all over the net looking for one, but I think I'm going to have to find someone that has one, and will sell me a copy. Any help would be greatly appreciated! Thanks-------------john :drinkup:

[jptech]

Well, never mind about the manual.... I found one for $100.00 from the company that reps a newer model. Nice guy.. didn't try to get me to buy their newer machine!!! --------john

[pulser]

:confused: $100 for a manual? Seems a bit steep!

I agree, but when you can't find one anywhere else.....! I only paid $100.00 for the welder. It's over $8000.00 new!------------john :drinkup:

[pulser]

Will it operate on 60 hertz, single phase, 110 or 220 VAC?
If so that is a great buy. Sorry about the manual though.

50/60 hz, 208/220/380/440 3 phase, .05-50 amp output. I can use it for micro tig, or, set it up for plasma. I'll go tig first since the plasma torches are over $1000.00!!! ------------ john :drinkup:

[fun4now.]

wow 1000 for a 50 amp plasma torch. you should have just put the $200 tword a new Miller. is the tig also only 50 amps?
$8000 for a new 50 amp any thing sounds a bit high to me, for $8000 you could have a new dyn300DX and a spectrum 375ext. and they would be single phase. do you have 3 phase or do you need a converter ??
not all deals end up being deals in the long run, just wondering how this one is going to pan out ??
how about an update ?

[Ries]

The reason the torch is so expensive is because this is a plasma WELDER, not a plasma cutter. Totally different beastie.
Plasma welding is fiendishly expensive, believe me, 8 grand is CHEAP.

And the low amperage is .05 amps- thats an accurate 5/100ths of an amp- most 5000$ tig welders will only accurately go down to maybe 5 amps.
So for micro welding, where you are welding tiny stuff, below 1 amp, reliably, gets VERY expensive.
This is a very high tech inverter machine, and at $100 its a steal.

It is not comparable to even a Miller Dynasty- in fact, it makes a $8000 Aerowave look kinda clunky, on the tiny stuff.

So paying a benjamin for the manual is probably a deal.

[jptech]

Once I have this thing up and running, I'll post pics and updates. Ever notice how going smaller costs larger??? I'd still like an Aerowave though!!!---john

I presume you got a good price because most everyday mortals bidding on E-bay don't have access to 3 phase power.

[fun4now.]

now i get it.;)
they had several of them for sail over on the shop floor talk site also, again low buy in price but no torches and stuff but i think his were single phase although i could be mistaken.
i supose if you want to weld at .05 amps its the way to go and the tool for the job, just not shore what the job would be.:p
best of luck to ya on it.:D

I think you're talking about the Miller Auto Arc 50A Tig welder. Nice unit! Mine's a different brand, and again, it has plasma capabilities. I'll be using it for mold & die repair with .005 filler wire. ------------john :drinkup:

[fun4now.]

no it was not a miller and it was a plasma welder.
looks like you have the right job for it, hope it all works out well for ya. show us some pic's when you get it up and running, i wana see this lil torch for doing .05Amp work. must look like a scribe with a cord.:D sounds like fun.

Hmmmm... the Miller was the only one I saw... have to look again!
Thanks! I'm hoping to do well...lotta mold shops in my area!
Go to Weldcraft, or just look for WP-50, or MT-125. Those will be the torches I'm using. I haven't used the wp-50, but the mt-125 is great for getting in real tight area's! ----------------john :drinkup:

Hi..., the one I have is for a 50-S. I don't know what the difference is, but it might give me more information than I have now. Do you have the welder too? Sorry about not replying sooner, but I just had someone ask me about the welder and, I just saw your post!-------John

[coolcruiser]

We have a Plasmafix 50E welder that came to us as surplus. It is missing the 13/2 pin foot pedal. Has anyone got a suggestion on what might work as an alternative? We have the W/D so an electrician could reverse engineer something suitable but that seems a bit tedious if there is a simple replacement. Any suggestions appreciated.

Goodafternoon Maria,

Don,t know of i am doing this the right way.

If i am correct reading the forum you are the owner of a manual for a Secheron Plasmafix.
Have you scanned the document and made an digital version of it?
And if you did, could i have a copy of this version.
Although bough't second hand from a factory who previous owned 10 units there was not one
manual in their technical support department left.

Goodafternoon,

Anybody out there?

There is not little reaction/response on this site, maybe i am using it in the wrong way.
Any respons is welcome, just for testing!

Still searching for manual and electrical drawings for a Secheron plasmafix 51.

From a different source i collected a sort of manual for a Nertamatic 50.
It is a similair plasma welding unit but with more advanced functions like a puls etcetera.
But torch connections, valve positions etcetera looking very similair as in the plasmafix 51.
Have not found any link on the web for this name.

I am also interested in "typical" problems solved by there owners.

Saw a question about a footpedal, i have a photo of the plate on my pedal.

Hello Bjorn,

Thanks for your reaction, i see your reaction here and on my private adress?

So i already anwered the question, always interested i a manual, but my machine is not so modern as the one you showed in your message.

I have learned already, from the Nertamatic manual there are several "checks" on parameters before the machine switches from pilote status to welding. Sometime the machine stays in pilote status, reason unknown. But i am getting closer.

Hello Peter.
You can try to contact oerlicon or air liquid welding and ask for a user manual.
i got mine for free. i have heard thath they have a problem with old models, but they have them on paper and maybe they can scan the part you need. maybe for free.

[P Dutch]

Hello Bjorn,

Have not looked at the site for a while, sorry.

Can try it with a direct reaction to Oerlikon.
If you get the manual for free, did you get it from your local country dealer or
did you send a request to the producer in Switzerland/Austria?.

I need to add a photo of my welding machine because the product name looks the same.
An old model Secheron Plasmafix 51 (no pulse or programmable tools).

Hello Peter.
I sendt a email to the office in germany,but they sendt the email to denmark and i got the manual from denmark.
What do you weld with your welder. I will use mine to weld jewellery and glasses(gold,silver,titanium and steel)

regards Bjorn

[P Dutch]

Hello Bjorn,

I am not a proffesional welder it is for hobby purposes only.
I hav e tried some second hand Tig welders but the minimum current is always too high for thin
stainless steel. So i bought second hand this 200 kg Secheron and thougt let's try ths thing.
It is more complex with the cooler, the torch, the risk of melding the torch etcetera.

And it is ....... more complex, there was a leak in the cooler, there was a leak in the connections of the torch and i had a electrical problem. But, it is also my first welder with a footpedal for regulation of the welding current and the weldings looking very good. But is is not a machine for "easy to use".

I am stil upgrading reliability and basic pilot arc settings. I am glad it is a hobby.

What do you use for Ar and Ar/H2 settings in Ltr/min?

Hello Bjorn,

Forgotten something; do you want to share the adress of the office in Germany?

The drawing (scheme) i have received of an other person is not for exactly this machine but code of the electric wiring is the same. So i have solved a electrical problem with it.

But i am building up a complete documentation of the machine, torch documentation, scheme, electronic components etcetera. With an adres i wil try to get an full electronic scheme of the machine. All the used components are standard materials.
But there connections and settings are interesting.

So i am 5% welder, 50% gambler and 45% technician.

Hello Peter

the adress is: info@oerlikon.de
but you can google oerlikon welding and click on the flag of different countries and take contact there.

I have only used my welder for one week.I had problems with the main voltage in my workshop it was to high,and i had to make a transformer to get the right voltage.
and i have a couple of other problems,
but i can fix it when i get the time to do it.
i have only one bottle of gas(argon 5.0)and only one regulatore.

it makes the gas flow a little unstable.

i have to buy one more regulator later. i have used a lot of money to buy the welder


The welder is not easy to use,but i have tested it on silver gold and titan,and it works,
but i want a learning book or som tablets for help to learn how to adjust the welder for different metals and different thicknesses.

Regards

Bjorn

hi again Peter

this is what i really mean about the gas qestion.

I have only one regulator,thath is the ting make the gas pressure a little unstable.

the user manual suggest 0.3l and 4.0l for a 15 A weld.

Bjorn

[P Dutch]

Hello Bjorn,

I have two bottles of gas Argon and Argon/H2 2%. The pilot Argon flow must not come above 0.5 Ltr/min otherwise you will burn the cupper nose of the torch (i have lost 4 of them). The shielding gas Argon/H2 is set for 5 Ltr/min. So this is about the same as your settings.

I am experimenting a lower setting of the Argon, because 0,5 Ltr/min gives me a an arc what looks a bit wide and a bit too hard. But lower settings makes it more difficult to start the arc.

In the look alike manual of my machine there are possibilitys to change voltage settings.
In the Netherlands the voltage has been changes over the last 15 years from 220/380V to
about 230/400V. Maybe you can make an adjustment in your machine?

I the last month i think i have solved the last problem in the machine. So i can concentrate on the welding settings. I am understanding the machine better every time.

Thank you fore the adress, i wil send a e mail and ask for a complete set of drawings of the machine.

[choke flange]

Gentlemen,

ended up on this site when looking for documentation on Plasmafix equipment. I have two Plasmafix welders, a 50-E and a 50-S and I have the same problem of not having any documentation on the machines. This is a problem as the machines are quite complicated to operate and adjust, but also because they are very intricate machines, with lots of electro-mechanics.

If anyone has some documentation on the machines I would be very grateful for a copy and for some sharing of experiences with the 50_E and 50_S

[Bjorn]

Hi choke flange

i am sorry thath i dont have ansvered earlyer,i have been very busy.
I only have documentation for plasmafix 51,but you can try to contact oerlikon welding.
I got my user manual for free there.
Whath do you use your welders for,i want to use mine to weld jewellery and glasses,gold,silver,steel and titanium.
It is not very easy to use,maybe it will work better when i finish my foot control ,maybe next month.


Bjorn

[choke flange]

Hi Bjorn,

thanks for your answer, any reply is appreciated.
To answer your question: I would like to use my Plasmafix 50E and/or 51 to do some repairs on tools that are to delicate to be repaired by ordinary TIG. I'll have to do some repairs on the equipment first though.
What's the problem with your foot pedal? Did the equipment come with a malfunctioning foot pedal, or are you making one to suit your 51?

Frans.

[Bjorn]

Hi Frans

I try to make a foot pedal with a potmeter and some mecanics.I only miss the cable plug and i hope it works.
What is the problem with your welders? Is it a electrical problem?Maybe you can use the wiring diagram for the 51 to help you.
Do you have a microscope for the smallest welds? I have problems to see the smallest parts.

Bjørn

[choke flange]

Hi Bjorn,

let me see if I can be of some assistance with your foot pedal (cable plug).

The problems are indeed of the electrical kind and since the machines are quite intricate, I do need the help of a wiring diagram. If you have one I'd be grateful. (I have a 50E and a 51). The power units seem to be similar as are the mechatronics (solenoids etc.)
As to my eyesight: I need glasses for welding anyway, unfortunately. As I took up welding again after not laying a hand on a torch for a long time, I was appalled by my poor welding. Reading glasses made all the difference :-)

[Bjorn]

Hi

Thanks but i have already ordered the plug from rs components.
If you send me your email adress i can send you the user manual for the 51.
The plasmafix 51 has been made in a couple of versions, so you have to seeif it is the right.
Do you have an extra ,small torch you want to sell,or if tou need a bigger torch we can change.
Have you any education in micro welding? I need a schoolbook or somthing to learn more of it.
I use reading glasses already,but maybe i dont use the right value of the glass in my welding mask.

bjorn

[P Dutch]

Hello Bjorn,

Reading your message about having a problem with seeing the welding spot because of low light intensity. I have had the same problem with a normal flash welding helmet 9-13.
But you can buy a flash welding helmet form "Speedglas" type 9100.
This type has two more dark settings of 8 and 5 + ofcourse 9-13.
You can look at your welding proces even at the lowest currents.
If you send me your e mail adress i send you a .pdf file with the information.

[Simon ARC]

Hi,

I´m Simon from Germany. I worked the last years very often with a micro- plasma welder in my job and last week, i bought my own one, a SECHERON PLASMAFIX 50 E. It is in a very well condition so far, i have also already a manual from oerlikon too (on PDF, if somebody need them). But my Problem is, i have no foot pedal and no gas equipement for my machine.

Could anybody help me, with a picture of the plate of the foot pedal, a electric drawing or any other information about the resistor in the pedal that it seems to be? I think, the circuit of the foot pedal is not very difficult, so i`d like to try to rebuild one...

I also need a picture or information of the original gas equipement. I dont need the pressure reduktion but the flow- meter.

It woud be great, if anybody could help me with my problems !! My email adress is: simonarc(at)arcor.de

Thanks, Simon

[P Dutch]

Hello Simon,

I have an older Secheron Plasmafix type 51 with a foot pedal.
I don't think it is easy to copy.
It is not just a resistor with a regulation mechanism, but there are switches also.
These switches are, for the plasmafix 51, to change from pilot arc to plasma (workpiece) arc.
So the connector is not a tree pin type.

If you have an .pdf of your machine with a schematic drawing you should be able to find it.
In my drawing regulation voltage 0-10V/0-50A.
I have made a picture of the frontpanel of te 51 and a picture of the plate on the footpedal,
and mailed it to your home adress.

Gr. P Dutch

[Bjorn]

Hello.
I have a newer model of plasmafix 51,and i have made a foot control.
To regulate the welding current i only needed a 1 K ohm pot. meter.
On the remote plug i also can put a foot start switch,but i can use the switch on the welding torch
to start the arch.
Simon were did you learrn to use a micro welder?
Do you have a school book or other material .courses...

Bjorn
