Mig wire diameter for sheet metal.

0 035 diameter wire 50 amps to 180 amps. From automotive parts to fabricated structures shipbuilding metal buildings and sheet metal applications all have often reaped benefits from the switch to mig wire. I have an older miller 180 mig that works great just wondering if anyone out there can recommend a good wire diameter 023 or 030 for what i m doing. There are many filler wire diameters available for mig welding.

Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal. This means the extra wire causes the voltage to drop by the time it actually gets to the surface and strikes an arc. You need to stay within these parameters. Advantages include slag free welding with less clean up even in multiple pass operations.
