I dont know where youre at but the ag newspaper Lancaster Farming
]. The paper has a swap and save section called The Maibox Market. Ive often bought things very cheap. They always have welders , both electric and gas for sale at deep discounts. Do you have a regional ag newpaper in your area? Id start there.
I have a 120 Ac and a gas welder. The biggest investment was the regulator and a cart and I ultimately got some of these for free. I do very little welding but when I need to, its always emergency work for my place or for a neighbor . Im certainly no expert (Im barely competent) , I am good at cutting though.
Welders are like exercise equipment, evryone who buys either really thinks they will really make great use of it.
