The MasterWeld 401 MSR is a powerful synergic 3 Phase 400 Amp Inverter MIG Welder for heavier fabrication and welding applications.
This Inverter MIG Welding machine has unique characteristics for MIG welding resulting in very low spatter even on mild steel.
- Manufactured in Europe to EN 60974-1, EN 60974-5 and EN 60974-10
- Latest inverter technology, lightweight, powerful and efficient.
- MasterWeld unique MAC (Master Arc Control) welding technology - extremely stable arc with minimum spatter and excellent weld bead quality
- With the latest microprocessor control and synergic curves in the memory locations, the customized welding parameters assure complete welding process repeatability
- Excellent on thin materials due to digital feedback control of the welding arc
- Wide range of MIG-MAG synergic programs facilitate the selection of precise welding parameters using any welding wires on large range of materials for mild steel, stainless steel, MIG brazing and Aluminium
- Friendly-user interface allows precise parameters setting using only one knob.
- 3T Special allows both Hot Start and Crater Filler current setting, for optimal penetration at start and crater filling at bead’s end.
- Additional parameters, Down Slope, Soft Start and Burn Back are included for perfect arc ignition and crater filling.
- Available Air cooled or Water cooled
- Fan on demand and Built-in Wind Tunnel protects electronic devices from dust and saltiness and improves reliability
- Push-Pull Gun applicable for better MIG aluminium welding
