[QUOTE="B&M Farms, post: 837421, member: 15666"] As long as you keep 7018s dry they will still make a good weld for the farm. The main advantage to a dc machine over ac is it is easier to make a smooth weld with. Ac uses a pulse arc that is harder to control. Ac can weld thicker metal at the same amperage though. When you price different welders look at the duty cycle. Most dc welders will have a higher duty cycle allowing you to weld longer without letting the machine cool down. I would want a duty cycle around a 100% at 120 amps. That would allow running 1/8 7018s or 5/32 6010s without stopping. It would take a little less amps on a ac machine to run the same rods. [/QUOTE]
