I bought a Eastwood 250 mig and can weld up-to 1/2” plus it will operate @ 60% . It cost around $850 .Have been using a 220 volt 170 amp cheap Mig welder without much success. I am looking to upgrade. I can't really justify the price of a Miller even though I know they are very well respected. Is there anything in the sub $700 range that will work for farm equipment.
