Hey everyone. It been a while since i been here.
So I still don't have a shop so all my welding is done out in the open. Been welding with a Lincoln Idealarc 250. Last year I purchased a little 120V YesWelder 135 flux core machine cool machine for less than $80.
Am thinking of buying a 220V machine mainly because every time I turn the heat on my little welder it keeps tripping the 20A circuit breaker.
I was thinking the YesWelder 250Pro. Wondering if anyone have experience with that model or any other cheap under 500 if possible lol.

Had the breaker tripping problem with my Hobart Handler 140.... Come to find out, it draws 24.167 amps (2.90 kVA) when running flat out.... Solution was to run a 10 gauge wire from 30 amp breaker to a dedicated 120 volt type receptacle ... And yes its legal if receptacle is labeled for welder use only per NEC......

Yeswelder gets great reviews so I've recommended them to a few people, my brother just ordered one of their dual voltage stick welders so we'll see on that guy... DC would be nice, his A/C transformer unit works but DC is nicer to use and lets you use 7018...

That said I have the Harbor Freight Titanium MIG 170 and Unlimited 200 and have ran them on flux core and on on 220 they work fantastic, I would expect a yeswelder to work similar, I have a friend that might of ordered that model and he says it welds great.

That explains why it keep tripping the breaker and i tried different outlets.
That's a great Idea, I am probably going to add this box with another breaker that way I can use the air compressor and welder at the same time even though I haven't seen the need to. And do the 10G wire and a 30A breaker on the 120V outlet

I've been using a harbor Freight for 20+ years. From when it was mail order! It's a cheapie, but it does all the light work that the Thunderbolt XL stick doesn't need to do. Also have a little Lincoln that was given to me for when I am in a 115v only place.

I have a Northern Tool Flux welder, several years old now. Only use it to tack up or really thin metals. It would trip on an extension cord with a 30 amp breaker.
I bought a 30’ 10g extension cord, cut the female end off and wired it to the welder. The original cord was too small for the machine.
Works great now.

I like the idea of providing a 30 amp circuit for that 120v flux welder.

110v welders can only output about 90 amps welding current on a household circuit. Some manuals for the (claimed) 135-140 amp 110v welders, reveal '30 amp circuit required for full rated amp output'.

When HF's Titanium 125 was backordered for months, I went to Amazon and got the similar Amico 110/220 dual voltage flux welder. $50 less than the (then) Titanium price. This Amico claims 135a output with either input voltage. But it trips the breaker on 110v annoyingly often. 220 volt input shows what it is really capable of. Now its rare to drag out the much heavier transformer-based HF MIG-180 for a project.

I think feeding 30 amps to your 110v Yeswelder will make it much more useful.

IF you are going to use that receptacle set, you will have to make adapter for 30 amp receptacle (NEMA TT30) to match to your standard 20 amp plug on welder line cord, or change plug on end of welder line cord...

Or something like this...
