The welder outlet is about two feet from the panel and the wires enter the panel from the side, away from everything else. Wired to its own standard 20a breaker and the common neutral and ground bus bars. No crossing or anything like that.

Another update; I hooked up and ran the second HF Titanium Flux 125 with no issues. I ran bead after bead on different power settings and neither of the two haunted AFCIs tripped. A couple of people had suggested cleaning and or tightening down the neutrals in the breaker box and it didn’t quite...

I’m following, but the two offending AFCIs don’t trip with my other two 120v welders even when set at max (80-125a) output. The inverter flux mig trips those two AFCIs even when turned down (40a or so), but doesn’t trip it’s own 20a standard breaker.

The more I think about it, the more it seems like RF interference or the like. There’s no way the welder is drawing too many amps, my dust collector pulls way more on startup. I picked up another welder of the same model (Black Friday sale :-) and still need to hook it up and see what happens...

I can certainly give that a shot, so you’re talking about the ground rod next to the house right? Anything special I need to do before messing with that, breaker wise?

Thanks again for all of the ideas and input. I’m kind of glad that my first thought of RF interference (or otherwise) might have been the culprit. Everything got stranger of course when I couldn’t duplicate the problem using power from the generator (which may have cancelled out the RF...

Panel is Cutler-Hammer and Eaton AFCIs, type BRAF, 15 amp.

Alright, so an update... but first, thanks for all the input and ideas. On a whim I connected the welder to my generator and ran it off of that to see if it was a wiring thing in the box. Figured if it was RF interference the circuits would still trip. Went for the gusto on full power and...

Howdy all, I have a problem that is perplexing me to no end. My garage has a single 120v duplex outlet, on its own 20a breaker, that I use for my 120v welders. Recently I picked up the new HF Titanium Flux 125, and while it is a great little welder, it trips the breakers (AFCIs I believe) on...
