I never welded in my life, but had some patch panels to restore my rusted out door bottoms. Rather than have it done for who knows what cost, I decided to buy the HF 90 amp flux core welder. It was a TOTAL success! Not bad for less than $100. I've also used it to restore my vent window frame (the lower threaded stud was broke off). I plan on also using it to weld in the side rails when I get to the bed part of the project. Jerry
