I just recently bought a Square Wave 200 to practice on pipe, both tig and stick. The machine runs tig and 7018 quite well. My problem is when I run 5P+ on it, it strikes up just fine, but I can only weld about a half an inch on a root before it terminates the arc. It's like someone just shuts off the welder while I'm welding. If any one knows what I'm doing wrong I could really use the help.

it is something to due with inverters and there Lower open circuit voltage. try some 6011 by lincoln i know its not ezactly the same but it will run on it.

Not all inverters have issues with 6010. I have no trouble running it on my TA 186 at home or with my little miller 150 STL at work. Or any of the several other inverters at work.

It likely has a low OCV/welding voltage, and once the Hot-Start switches off, so does the arc. Just my guess.

Thanks.
I guess I'll spend some serious practice time with 6011 and maybe some 7018, then come back & try 6010. From what I've read, I won't be surprised if Oscar is right.

I've run hundreds of pounds of 6011 on AC, some on DC. 6010 is less familiar to me. My Dynasty runs it fine. I'm not sure I could tell the difference.
