Xtrweld 415-3545TLM Mig Gun 400 Amp 15 Feet

Product Description

The XTRWELD 415-3545TLM is a heavy-duty MIG welding gun rated at 400 amps, built for demanding industrial and fabrication applications. The gun ships with a 15-foot cable assembly, giving welders working distance from the wire feeder without sacrificing arc performance. It accepts wire sizes from 0.035 to 0.045 inches through a Tweco-style liner, and connects to Miller wire feeders via a Miller backend power pin. Tregaskis-style consumables are used at the front end, keeping replacement parts straightforward to source. At 11.8 pounds, the assembly is built for sustained production use rather than light bench work.

This MIG gun is suited for structural fabrication, heavy plate welding, shipbuilding, and manufacturing environments where high duty-cycle performance is required. The 400-amp rating supports solid wire, flux-cored, and metal-cored processes in the 0.035 to 0.045 inch wire range. It is intended for professional welders working with Miller-platform wire feeders in shop or field settings where long gun reach and robust consumable availability are priorities.

Key Features

• 400-amp output rating for high duty-cycle welding applications
• 15-foot cable length provides working distance from the wire feeder
• Compatible with 0.035 to 0.045 inch wire diameters via Tweco-style liner
• Miller backend power pin for direct connection to Miller wire feeders
• Tregaskis-style consumables at the front end for broad parts availability

Compatibility

Designed for use with Miller-platform wire feeders using a Miller backend power pin connection. Accepts 0.035 to 0.045 inch wire with a Tweco-style liner. Tregaskis consumables are used at the front end.

Installation Notes

Installation should be performed by a qualified welding technician or electrician familiar with wire feeder systems. Power down the wire feeder and disconnect from the power source before connecting or removing the gun. Verify that the backend power pin seats fully and that all liner connections are secure before resuming operation. Follow the wire feeder manufacturer's guidelines for gun connection torque and inspection intervals.
