Welding woes...frustrating!!
Nice Hobart Handler 140
110v Unit gas wire feed
Good for 1/8" and thinner material.
3/16" is a stretch unless you preheat with a torch so it will burn in better.
Mixed Gas, Argon/Co2 works well.
Can always borrow, rent or buy a basic
220 volt Buzz Box Stick Welder for weling the thicker plate steel and angle iron.
