PRO MIG Gas regulator adapter...

[elvergon]

I have some Q's, hope you guys can help me out...

I went today to the welding shop and get the adaptor for my regulator kit, which my MIG included.

Now...I´m on a dilemma.... (I don´t know the name of the parts so I´ll just call them as what they look like)...

Regulator included a "bolt" adaptor which at the end has a spherical/conical end (you´ll see it on the pic, same as used in Oxygen tanks)...and a male nut at the end...Just like an Oxygen regulator...

What they gave me for fitting into the CO2 was another bolt like but it ends flat. It has an octagon shape...and a female nut.

Trouble:

The bolt adaptor the regulator came wich is Fine thread...and a little bigger than the one I bought.... (on the nut it reads "Argon-Helium-Nitrogen- CGA 580")....Since the nut is male it won´t work in the tank (tank is male). Now, the parts I bought are CGA 320 and hole on the nut is a little smaller.

Situation: Welding shops are closed by now...and I want to try this now...

Could I just use the standard spherical/cone bolt and use the other nut (CGA 320) just making the hole a little bigger? Is it really neccesary to have the flat end?

You could see in the pics what I meant...

I´m really in the need to test my MIG now...But I sure want it to be safe...cause tank will be on my little room...

PIC #1 shows the regulator...here you can see where the 580 Fine thread bolt should be inserted...

this is the "spherical/conical" bolt...and the male nut the standard Lincoln kit includes (CGA 580)

[elvergon]

This is what I need to adapt to the tank I have... CGA 320...Bolt is a little smaller than the one Lincoln gave me... and nut is female type...As you can see it end flat and has an octagon shape..

[elvergon]

the 2 type of bolts...

What I plan to do is use the spherical/conical that adapts to the regulator and use the other nut just making the hole a little more big. However only issue I can imagine is that CGA 320 ends flat and the other ends in the mushroom type end.

[elvergon]

Last one...the 2 kits...however CGA 320 fits the tank but not the regulator...and CGA 580 the other way...

Anybody??

last pic..

set-up on the left on the screen...:cool2:

i've never seen a set-up like that on the right for tanks..



...zap!

Here´s a shot of the tank....

[elvergon]

I ground the nut...and had the "bolt" of the regulator (the one the kit came with the spherical and conical) inside of the nut... here´s a pic...

Does it looks safe to use it?

[elvergon]

When I was trying to see how it fitted I open a little the valve...gas started to escape throu the corrrect path...So I said k let´s do this...now when adjusting the bolt to the regulator I broke the out gas line =( I think it´s time to take it easy on the gym...

NOW I need a regulator =( that SUCKS!

Thanks for the help anyway...

[elvergon]

here´s the broken part...seems like its a no replaceable one

[zapster]

the first pic of the tank...
wtf?

looks like right handed threads on the outside..
and left handed inside??

That´s right bro...

It also got me wondering how would people use that inside thread...seems to be too small to hold a hollow tube for letting CO2 pass...pressure would knuck it


BTW thanks for helpin ;)

thats not right you need to use the other stem with that nut

[elvergon]

Aye thnks chopper... Since I broke the regulator now I need a new one...so I´ll get the correct one ;)

Thanks
