Here is what you can set yourself up to make decent money fixing trailers, trucks, farm stuff.

Tapatalk is going to put these in a weird order but what I have.

AC/DC 225/125 stick welder. Will do sheetmetal in a pinch up to most any size steel found in trucks, farm equipment etc.
$695 MSRP. Can be found for less.
Had since 1990.

Hand carrryable 230V Mig welder.
Mine is WeldPak 155. Modern replacement would run about $750-1000
Use mostly for auto body and similar sheet metal or thin stuff. Can do aluminum and stainless steel but I use my TIG fir that.
Bought in 1997

Big heavy bastard TIG
Lincoln TIG300/300. Will go up to 400A on AC stick welding. I use it for TIG for doing brewery piping, and a lot of dirt bike repair and construction. Can weld any weldable metal with it. Modern equivalent is 1/10 the weight and 1/4 the size provided you dont need over 200A. Have had multiple of this model. I like the old transformer based machines for very thin stainless.

Torches. Had these since 1989.

If you want a gift that keeps on giving, get a new welder a GOOD auto darkening helmet.

I like the Lincoln Viking with C4 lens.
