- Production fabrication shops — sustained heavy-amperage MIG work on thick mild steel and structural members
- Heavy equipment repair — capable of full 100% duty cycle output on mid-range jobs
- Structural and pipe welding — three-phase input handles continuous-arc demands without thermal cutout
It supports Stick, DC TIG, Pulsed DC TIG, MIG, Pulsed MIG, Flux-Cored.
40% @ 550A, 100% @ 450A (GMAW). This means continuous welding at that amperage for the listed percentage of a 10-minute cycle before requiring cool-down.
200-600V (208/230/380/415/460/575) on 1/3 phase power.
0.023 - 0.062 in (0.6 - 1.6 mm) dependent on feeder — covers standard MIG wire sizes from sheet metal through medium structural work.
