Don't buy a cheap welder. My son, recently, 1-2 years ago, graduated from Tulsa welding school and the instrctor told them never to buy anything less than a 180Amp mig. Anything less and they would be dissapointed. I proved that correct and went through 3-4 cheap welders b-4 I learned. Sheet metal like on these trucks require at least a 130Amp mig to weld. After using 3 cheap welders I borrowed one from a friend and it worked. (130Amps) Then I bite the bullet and buy a Lincoln 180Amp mig. Best thing I ever did. It works great especially for a beginner because u are starting with the right equipment. Just get a good welder and practice. It's alot like painting. You just "read" what it's doing and adjust accordingly. Any welder will tell u PRACTICE-PRACTICE-PRACTICE!!!
