That's what I have for home use. Excellent MIG, decent TIG and stick. Nice for aluminum (spool gun). Versatility and portability are nice. Duty cycle is too low for production work, but all right for home projects. What were you planning to use it for?
Well yesterday I had a thought, more of a dream really. I was riding my motorcycle with some people and came to a line of people sitting on their bikes on a bench, like a church pew. I tried to squeeze myself and my bike past everyone to get to the other side of the bench thing. When I got to the end my bike was gone. Same color bike was in my hands but it wasn't mine. A buddy picked me up and we went riding around looking for who took it. We stopped at some sketchy shops that sold bikes because we figured they would be selling it as stolen. No dice. I don't remember the rest but I never did find my bike. Anyway hope to hear your thoughts on this as well. Maybe we can share more thoughts in the future. Headed to sleep now, maybe I'll find my bike tonight. ttyl
I recently bought a 70 amp portable welder that runs on a normal household outlet. Planning to use this to learn some welding fundamentsls. Will I be able to get enough penetration to weld on .25" channel and square tubing?
you kinda fucked up, but you can find plenty of thin scrap to practice on. I hope you werent planning on welding anything thick though. google the amperage to thickness charts and see. 70 amps is like 1/16th territory
A nicer inverter welder can weld quarter-inch just fine on 120V. OP's mentioned welder can do 150A with stick on 120V-20A.
70A is not going to get much penetration, but you should be able to multi-pass it. Just be careful about insufficient fusion. Preheating with a blowtorch can help with that.
Visit professional welding forums like weldingweb and the Miller forums (they cater to other brands too) to get user opinions.
I suggest weldors go there because NOTHING in /diy/ comes close.
Miller also have free training videos. Both have people like self who have lots of welders of different brands so you can compare to get what will serve your needs.
All I'll add it "you can't turn on amps you don't have".
Miller make excellent machines. Now go ask people who own THAT SPECIFIC Miller how it performs on tasks which match YOUR desired use case.
It's easy. If you visit the Miller forums they won't eat you through the internet.
Is that so hard?
BTW Miller and Hobart share a parent company and have many comparable models. When Hobart broke up Thermal Arc and Hobart had to spit the business or Miller would have had no competition and the Feds would have blocked the merger. Many parts interchange too.
