Tweco 1036-1642 Mig Welding Gun 350A 25 Ft Miller

Product Description

The TWECO 1036-1642 Spray Master is a 350-amp, air-cooled MIG welding gun built for spray transfer and pulse welding applications. It features a compact, ergonomic handle and a thick-walled, three-layer conductor tube that improves electrical conductivity while acting as a heat sink. The 25-foot power cable is paired with a fully insulated Miller drive-style connection for quick connect and disconnect at the wire feeder. Designed for heavy industrial use, it handles wire sizes from 0.045 inches to 1/16 inches and delivers an 80% duty cycle when used with straight CO2 or mixed shielding gases.

This gun is suited for shop, production, and maintenance and repair environments where extended run times and ergonomic performance matter. Its balanced pivot design centers the gun at the handle, reducing operator fatigue across multiple welding positions. The extended trigger length keeps the operator's hand back from the arc to limit radiated heat exposure. Applications include farm, garage, shop production, maintenance and repair, and artistic metalworking where spray transfer or pulse welding is the primary process.

Key Features

• Thick-walled, three-layer conductor tube for higher electrical conductivity and heat dissipation
• Heavy-duty contact tip and diffuser extend tip life and reduce downtime during tip changes
• Balanced pivot at center of handle reduces operator fatigue in varied welding positions
• Extended trigger length reduces hand exposure to radiated heat from the arc
• Steel spring strain relief minimizes wire feed issues at the rear of the handle
• Split-half handle case allows field repair access without special equipment
• Interchangeable front-end consumables compatible with Tweco Classic No. Series and Tweco Spray Master Series

Compatibility

Equipped with a fully insulated Miller drive-style connection for quick connect and disconnect at Miller-compatible wire feeders. Front-end consumables are interchangeable between the Tweco Classic No. Series and the Tweco Spray Master Series.

Installation Notes

Installation should be performed by a qualified welding technician or electrician familiar with MIG welding equipment and applicable NFPA and NEC standards. Disconnect and lock out all power to the wire feeder before connecting or disconnecting the gun. Verify the liner, drive roll, and contact tip are correctly sized for the wire diameter being used before initiating a weld. Inspect the cable, connections, and trigger assembly for wear or damage at each service interval.
