Help with wire selection...

admin

Alright guys, heres the dilemma...I need to weld some bumpers for a jeep this weekend. I only have access to a mig machine and need to know what kind of wire would/will work best for my situation.(Im a stick welding guy, so dont know too much bout mig wire yet)The bumpers are 2x4x 3/16 wall  main channel steel.I will be doing these outside in the open with little to no protection from wind. From what Im told, I wont have access to gas either Any help is appreciated guys! Thanks in advance!-adam-Beer is proof that god loves us and wants us to be happy!

Reply:I’ve used Hobart FabShield ER70T-11 with good results. Remember to change the polarity from MIG to Flux core.
