110v welder problems

[brans72]

I have a 110v welder with gas and seems from what I can tell at times it dropping amperage and not melting wire fast enough leaveing crappy welds. Also when welder is messing up it trips breaker (tried 2 different breakers circuits). So when seems to do amperage drop wire starts to skip/jump/pop. So anyone wanna help? Yes ground was good in my book,new metal was raw unfinished 18 gauge to old metal on truck bed that was cleaned very good before welding. Can say ground wire is wire from like car quest and is thick, just does not bend easy and sucks to try to roll up. Thanks in advance Brandon
