hello im looking to figure out what welder is best to help my buddy fix up his 92 GMC sonoma truck bed its rotted away and needs to be repaired. ive found a few reasonably priced welders but i need to know what would be great for this job. im not an expert on welding but i have welded in my home garage growing up. we used a gas mig welder and it got the job done fairly nicely. now im looking to purchase my own. what would be best for our project? gas mig or the gasless flux? ive never used a flux and i have no idea what its capable of. all input is welcome
