So how much amp do i need for my circuit breaker to be able to run pretty much any 120v welding machine. my 125 flux core chicago electric runs fine. But my stick welder blows the circuit 2 seconds after striking an arc. It has a weird chart it looks like its a 110v welder from the chart but pulls 40amp. So thats why i am asking how much amps should i buy for a 120v welding machine, my aim is not to get a specific welding machine to work but so that i can buy pretty much any 120v welding machine and use it. My uncle is an electrician so i trying to figure out what i need him to ask to install.Trained InGMAW 2G (Horizontal)FCAW 3G Vertical and 4G OverheadSMAW 3G Vertical and 4G OverheadGMAW(Pulse) 3G Vertical and 4G OverheadGTAW (INTRO)Carbon Arc Gouging (INTRO)Weld Symbols (INTRO)Distrotion ControlOxy/Fuel Cutting (INTRO)
Reply:That is problem with 120 volt weldersMost homes have120 volt circuit are 15 or 20 amp.But they need a 30 amp breaker.If read Forney some they data will show a 30 amp 120volt circuit.You may want check company that made the welderOthers just used one leg of dryer plug note they had a 4 wire dryer plug.I fixed the problem selling the 120 volt welder by buying a 240 volt welder.Good luckDave

Reply:If you are going to the trouble of running a heavy 120 volt circuit why not just go 240? It's the same amount of work and the same number of wires. A 120 volt welder will constantly be a limiting factor to what you can do.Miller Challenger 172Miller Thunderbolt AC/DC 225/150Miller Maxstar 150 STLVictor 100CVictor JourneymanOxweld OAHarris O/ASmith O/A little torchNo, that's not my car.
Reply:I agreeI try the 120 two times I just gave up on 120 welders I was uses to good 240 volt welder and the 120 just did not cut it.Dave

Reply:Definitely consider 220 as mentioned. If that's not a option I would run wire for your highest amps to a fused disconnect with outlet. You can use fuses to match machine. Sent from my iPhone using Tapatalk
Reply:With a decent 120 volt stick machine you can generally have zero issues running about 95 amps output Some 120 volt breakers are more forgiving of snapping ,and will run fine with-in the duty-cycle of the machine.. So change your breaker first.. I have setup a pretty nice 120 volt system with a small plasma cutter, Tiny stick welder, and a flux only mig unit that is flat out awesome. Yes, I can run other stuff on 3 phase 240 and have more output, it just will not travel anywhere as well. Cost To Performance/size is really off the charts if you buy well.Esab/Lorch ET-220iEsab 160i caddyThermal LM-200 Lincoln feedersThermal Pee-Wee 85sThermal 60i- 3phase /RPC powered (Beast)Thermal Drag-gun 35CINE 1500 Klutch 140i
