Magnum® 400
With a longer gooseneck and a higher copper strand count cable than the 300, the Magnum 400 gun is built for operator comfort when welding with the greater heat levels generated by higher amperage applications. Select the 400 for most .045”, .052” or 1/16” MIG, UltraCore or Metalshield (gas-shielded) operations.
