140 Amp Machine on the Way!

[gaustin]

I have the 140 amp stick welder on the way. Were gonna see if this baby will burn a 1/8" 6010 and 7018 good enough to weld a pipe.

A 60% duty cycle will keep up with me, will just see if it things are as advertised.

I hope so.

[ironman715]

What brand?

[gaustin]

Longevity.

[Broccoli1]

What brand?

I assume Longevity since this the Longevity section:drinkup:

Gerald,

Good news! I was able to get your unit out today and made sure the guys here packed it very well! The DHL tracking number is under your order number.

Let me know if there is anything I can do after the unit arrives.

That's cool to see an official (I am assuming its official, certainly appears to be) response from the company. That kind of individual attention says a lot about a company.

Just wish more companies understood/had time to do this.

I'm looking forward to it. I am hoping to look at it as a welder that is advertized as being able to produce a certain output and NOT as a low cost alternative to other products. I beleive the rating was 60% at 120 amps. With a normal welder that is adequate to burn a 1/8" E7018 in the vertical position. However if this one has reduced voltage to achieve the higher amperage rfating, it won't work.

We will see. Thats why I am interested in the operators manual with specs for that EXACT model.

Gaustin

Why did you decide on the 140 amp instead of the 200 amp tig unit?

[gaustin]

Mainly because I am cheap. I figure if the cheapest one works well, the others will too. Of course with some of the other imported chinese stuff, you very well may get a variation in batches. Without knowing who the MFG is and if they have a quality system of any kind, Its hard to say.

I am interested in making a few welding videos and actually starting to do some training here. I talked to both of the importers of this type machine and the other didn't have any in stock. The other company made a real good offer on a higher rated machine and I hope he will contact me when it comes in.

I made a good deal with the guy at Longevity to try out the machine at minimum risk to either of us. If it works well, I will look into buying the larger machine.

I still want to look at the ones from Everlast and was made a good price on one of the larger ones but the boat hasn't arrived yet.

I have a little 80 amp harbor freight machine that is great for the price and size. Fixed the exaust on my 85 Nova/Toyota a week or two ago with it and it was great for burning the 5/64" 6013's.

Both companies seem to have some issues with each other. I'm just interested in the welders.

[tapwelder]

There may be a misprint on their site. The prices are the same, that is the reason for my question. Perhaps they are the same maching just 200 amps if you tig. I don't know...

$350 is a good price for a 160 DC amp machine, if you got better than that then congratulations.

[tapwelder]

Sorry gaustin

I was not making the distinction between Longevity and Everlast. I was on Everlast site. Disregard the last post.

[gaustin]

I dont think everlast has anything in stock? Or at least thats what I understood. When one comes in I hope to get one. The price I was sent was excellent.

As a smaller company compared to the huge corporations out there, we understand that customer support is the most important aspect of our business. We constantly keep our customers updated with their order and stand behind our service and products.

You are more than welcome to try out our units!

Thanks

The machine came in today and I was able to burn a few rods. On the outside everything looks good. I ran a few beads with some 1/8" 6011 and they seemed to burn OK . On the lower end (75 or so) it seemed like the arc would go out easily if I whipped out of the puddle much. Up around 100 it welded fine with no apparent problems.

Hope to weld some more in a few days but have a busy few weeks coming up with VBS and vacation.

Great to hear you got the unit. The welder has an amperage sensitivity setting. I will see if I can provide you with a picture on how to adjust that. I know our latest models are all equipped with that feature.

Please post some pictures and videos. Im glad the unit is working for you.

Simon

[gaustin]

I have never heard of an amperage sensitivity setting. Just the amperage. Is this something internal ?

[longevity-inc.com]

Yes,

It is internal. Looks similar to this:

Check to see if your unit has that setting. It allows you to fluctuate the current at different amps.

Hope that helps.

[gaustin]

I am still unsure what it does. Current and Amps are the same. Does it change the voltage at a given setting ?

I will provbably weld with it some as-is. Its not to bad. The arc just seems to go out easily if the length is incresed. Lengthing the ARC increases the voltage and the machine may not be keeping up. It (whipping) is a technique used with electrodes such as 6010 and 6011.

[longevity-inc.com]

If your arc fades out that setting will allows you to regulate current so the arc is stronger at lower amps. I am not positive your unit has it, but most of our production units do.

Look forward to seeing some pictures.

[gaustin]

I had some time today to burn a few rods with the welder. It is a pleasant change from my 80 amp inverter. I have it plugged into a 50 Amp 220 but it seems to cut out. It welds along fine for a few seconds, then the arc goes out and then right back on. I am welding with 6011 and I whip them slightly but not enough to get more than 1/8" or 5/32" of arc length.

I burned 5 rods back to back and it seemed to get worse. I had to really tighten up my whipping to almost none. I will upload some video of what happens in a little while.

[longevity-inc.com]

gaustin,

I am checking to see if a 50 amp plug is too much for the unit. I believe it doesn't draw that much power.

Hope to have a reply soon.

Simon

[gaustin]

I think the 50 Amp will just Allow for a 50 Amp draw but doesn't affect anything requiring less amperage.

I have a page up with a few pics of the machine and a link to a page with a flash video.

http://weldingdata.com/WelderReviews/longevity/LongevityMMA140.htm

Excuse the video quality aas I had some technical issues. Watch for flashburn on that 4th rod. The video shows 4 consectutive rods being burned. By the time I got to the 4th the arc became a little unstable. I was using brand new Hobart E6011s right out of the box. These are typically very forgiving.

cool... post pics of your first welds with it

??????????:dizzy::dizzy::dizzy::dizzy:


So lemme get this straight, I'm having a hard time here ....... you are saying,,,,,,, if you plug the machine into a receptacle with TOO MUCH available amperage, it will not work properly?????????? :dizzy::dizzy::dizzy::rolleyes::rolleyes:


I think you yourself should go attend a basic sophomore high-school electrical course ........

[gaustin]

cool... post pics of your first welds with it

Here is what I could get out of it earlier this AM. Still cutting out randomly.

I don't have any 1/8" 7018 right now but hope to get some this week and see what they can do.

I checked all of my connections again and no hot spots that would be evidence of a bad connection.

I don't have an AC Ammeter so I can't see what it is drawing.


Have a nice day

Gerald,

I will contact you on Monday with some of the welding problems you are having. If we cannot find a solution to check over the phone, I will replace it and cover all shipping charges.

I am sorry you are experiencing problems.

PS: The video is a little dark, but the pictures look nice.

[gaustin]

I have been able to run a few more beads with the machine. I welded a handrail for a friend that recently had knee surgery and the welder worked well but I haven't had much time to really test the welder yet.*
During testing using some E6011 I had problems with the machine cutting out. I beleive I found the cause in the ground clamp. The picture below is what I think was causing the problem. I have since replaced the ground with one from a HF machine but have yet to retest using 6011.

http://weldingdata.com/WelderReviews/longevity/groundclamp.JPG



I did get a chance to run a few 1/8" E7018 prior to going on vacation last week. I just ran a few beads inside a piece of 2-1/2" x 2-1/2" x 1/4" Angle. The welder did not cut out at all and the heat seemed consistent throughout. A true test will be 6 minutes straight of welding and then 4 minutes off.



Below is a picture of a few beads run verical up. These were made to show what the welder would do. Not what the WELDOR can do. I have made prettier welds in harder places and uglier welds in easier places.

http://weldingdata.com/WelderReviews/longevity/VertUp2by1_4Angle7018.jpg


Again, anyone with a Red, Blue or Yellow inverter that weighs within 10 LBS of this one is welcome to do some testing with me. Flat, bead on plate 1st to check out the duty cycles, then a few butt welds in plate and pipe.*

[gaustin]

Below is a slideshow showing a multipass fillet weld on 1/2" plate made with 1/8" E7018.

This was all done with less than 20 seconds between each electrode. The machine did not seem to fluctuate any during the weld. The 6011 pass made on the 1st bead welded nicely and the arc went out one time at the top. This could have been the result of me not paying attention to the arc length.

I made a few updates to the review ppage for the MMA 140 welder. http://weldingdata.com/WelderReviews/longevity/LongevityMMA140.htm

The machine I have seems to meet the duty cycle listed on the machine. Without an ammeter its hard to be certain. I did post some pics on another section of the forum bit they are one the page . The main point of the test is the fact that the welder was able to weld with the power turned all the way up for a period of time that exceeded the duty cycle rating.

I also dropped it a couple of time and it continued to weld. Here is the video of the actual dropping .http://weldingdata.com/WelderReviews/longevity/long140drop/long140drop.html

[gaustin]

I was able to setup a tig rig on the machine at lunch today and weld a few beads. Also updated the review page. http://weldingdata.com/WelderReviews/longevity/LongevityMMA140.htm

Here are some pics.

Gaustin,

Thanks for showing us your work and informing those people on this site who are interested in our equipment.

You have done a fair and great job with your reviews both on here and on your website.

Simon
