Xtrweld 40015116TLM Mig Gun 400A 15ft Miller Rear

Product Description

The XTRWELD 40015116TLM is a heavy-duty MIG welding gun built for high-amperage wire feed welding applications. Rated at 400 amps at 60% duty cycle with CO2 shielding gas, this gun delivers consistent performance in demanding shop and field environments. The 15-foot cable is manufactured in the USA and features heavy-duty spring strain reliefs at both the front and rear to promote smooth wire feeding and reduce cable fatigue. A 360-degree rotatable gun tube allows out-of-position welds without repositioning the feeder. The bladed trigger design is built to outlast standard microswitch triggers over extended service life. CE certified for safety, duty cycle rating, and insulation integrity.

This gun is designed for use with Miller-compatible rear-connect wire feeders and MIG welding machines. It accepts 1/16-inch wire diameter and is suited for production welding, fabrication shops, and heavy repair work where sustained high-amperage output is required. Compatible with Miller S21E, S22A, S32, Super 32, Extreme 12VS, all 50, 60, 72, and 74 series feeders, 8VS, 12RC, 12VS, and R115 feeders, as well as Millermatic 300 and 350 machines. Installers and welding technicians working with Miller feeder systems will find this gun a direct-fit replacement option.
