We have 11 of them in our body shops for close to 3 years now. Only one failure on one of them and it wasn't the actual solenoid it was the switch in the torch. We use these every day . Multiple times a day. We use them for cusi silicon bronze also and the spool gun for aluminum. Our guys love these machines . We have a few big Lincolns and millers that just sit in the corner now .

Man I have a hard time running mine. I have to turn it up so high ( 3/32" 90 amps) to keep from snuffing out it acts like an arc gouge.

Ive had my omnipro 220 for 3.5 years now. Ive gone through multiple bottes of c25, and 20lb rolls of 70-6 and ive had absolutely zero issues with the machine. Ive stick welded many times with it as well. My buddy borrowed it to run stainless on, and he loved it so much he went and bought one for himself. Highest quality machine on the market for the value in my opinion.

I got mine on sale in June as an upgrade from my EasyFlux 125. They wanted $279 for a two-year warranty, which was crazy. Now it's down to 90 days! Unfortunately, its circuit board died literally on day 91 since buying it, where it would no longer expel gas and wire feed (even cold wire feed). Fortunately, they exchanged it for a fresh new one the next day (technically past the 90-day warranty) at the second store I tried, so I dodged a bullet and was not stuck with a waay-overpriced stick welder. Hopefully the replacement won't die on me. There is another content creator who reviewed this model and also had its wire feed die early on. AI (FWIW) does not suggest this model has a high defect rate. I just maybe drew the short straw.

And so the wire feed and gas exppulsion died on Day 91 after purchase. THe second store I tried let me exchange for a new one. HOpefully the new one won't die as well. (They wanted $279 for a two year warranty- which is insane)

Update. The wire feed (including cold feed) and gas expulsion for MIG died literally on day 90 after purchase). They still honored and let me exchange for a new one on day 91-92. Hopefully the new one won't die. (THey wanted $279 for a two-year warranty!)

My 220 that I bought when Harbor freight had Vulcan for 30% off, had the circuit board that controls the solenoid for gas and the wire feed die literally three months to the day after I bought it, technically a day beyond 90 days. Fortunately, I was able to exchange it for a new one that works… So far. Another day I would’ve been stuck with an $800 stick welder. I thought the $280 extended warranty was crazy expensive.
