- Production MIG welding — built for high-output continuous MIG work on mild steel and stainless
- Fabrication shops — runs flux-cored self-shielded wire for outdoor and dirty-metal applications
- Light-to-medium structural — handles 3/16" to 1/4" base metal with appropriate wire selection
It supports Flux-Cored (FCAW), MIG (GMAW).
20% @ 90A. This means continuous welding at that amperage for the listed percentage of a 10-minute cycle before requiring cool-down.
120V on 1 power.
0.025 - 0.045 in — covers standard MIG wire sizes from sheet metal through medium structural work.
