Question to all the welders out there!!!
Flux core is splattery but i dealt with that for years on automotive as well as fence lines lol. i converted mine to mig. Flux core can be workable but mig is the way to go on automotive sheetmetal. I can still switch mine out to flux core in just a few minutes by disconnecting the gas, installing the flux core wire, and swapping the leads inside the machine. Then i can go do fence line work and still have the portability.
Whatever you buy get something that has a true variable setting for wire feed and not a click type setting for wire feed. This lets you fine tune your wire speed so its not too fast or too slow.
