Here is the problem..... I have a 115 volt wire feed MIG made by Lincoln. It is rated at 20% cycle 60 Hz. 20 amps. When I am at the house I plug it in and the only place I have is a 15 amp line. After welding for a 10 - 15 second stretch it might kick off the breaker. It will kick off the breaker if I start a new weld right away after the first. ??? Am I making sense? Well I thought it might be because I was on a 15 amp breaker line. But when I took it to work I used a 20 amp line and it would weld fine the first pass but when I started a second pass right after that it kicked the breaker off again. What am I doing wrong? Any suggestions? Please help.
