I have to replace my floor pans in my 68 coupe, lot of little holes, I have decided to cut out the floor and put a complete new floor pan in it. Im new to Welding, my girlfriend has welded before she is going to help me (she is a keeper!) But im not sure what welder to use. I can pick up a cheap welder at Harbor Frieght, I can choose from Flux wire welder, Arc, and Mig, I can solder computer circuit cards under an 8x microscope to class 3 (highest quality level) so surely I can make a decent looking weld. Im just curious what the best type of welder to use for this. Thanks for comments.
