I am gonna try to keep this short, I always seem to write a book when trying to explain, so... I'm just getting my welders running after wiring my shop, the miller mig calls for 30 amp breaker which I have in my sub, 80 ft from main with 6awg aluminum plus one bare 10awg ground. Everything was good until I bought a 50 amp welder, I welded with it on 100 amps, no problems and my stinger was stuck to my table and it tripped breaker, but now I think my breaker is bad, it's floppy.. So here's my issue, my miller is 30 amps, my lincoln is 50, I definitely don't want to burn up my new miller so I guess I'm buying a new subpage and a 30 and a 50 amp breaker, and more wire and another plug for stick welder. The 6awg aluminum calls for 55 amps but doesn't give a length it'll hold the 55 I'm sure there's math involved but I'm right around 80' from main panel to sub, the lincoln ran fine on 30 amp breaker until it stuck to table, is it OK to run it off 30 amp breaker and just make sure it doesn't stick and draw over the 30? I really didn't expect to get two welders but hey, it happens, so anyone have a more simple solution? I gotta go buy a 30 amp breaker today so may as well get everything. The breaker is older itp and I've read I can use a qp style Siemens, same in the main but I haven't had problems with it tripping so hope this doesn't sound like jibbrr jabber and someone gets what I'm saying.
