Greg made a good point about combination welders.
When I was a wee lad of 19, starting my first chassis shop business in 1982, I needed a MIG welder & a TIG welder. I was short on money ... and short on experience buying equipment.
I bought a "combination MIG/TIG/ARC welder."
It could do all 3 ... poor to moderately ... but none of them well. In short order I had to buy a dedicated quality MIG welder & a dedicated quality TIG welder. I later sold the combo welder for pennies on the dollar.
What I got out of the experience was wasted money, time delays and an education.
