Magnum® PRO Semi-Automatic MIG welding gun with 250A 100% mixed gas duty cycle.

The Magnum PRO 250L is the most durable gun of the Magnum PRO L-series family. With sufficient amperage for bigger jobs, the Magnum PRO 250L is recommended for medium duty job shop and production applications.

  • 100% Duty Cycle - The 250L runs at 100% duty cycle using mixed gas, helping it withstand tough jobs
