Tweco 1036-1787 Mig Gun 350A 25 Ft Air Cooled Gmaw Fcaw

Product Description

The TWECO 1036-1787 is the VELOCITY2a Spray Master V350 MIG gun rated at 350 amps with a 60 percent duty cycle and a 25-foot cable assembly. It is air cooled and ships with VELOCITY2 front end consumables pre-assembled. The gun accepts wire up to 1/16 inch and uses a Tweco rear connector for straightforward connection to compatible wire feeders. Licensed HVAC and welding professionals recognize the 42 Series conduit liner as a proven component in high-output GMAW and FCAW setups. This gun is suited for production and heavy fabrication environments where arc stability and consumable longevity are priorities.

The 1036-1787 is designed for GMAW, FCAW, and aluminum GMAW applications in both shop and field welding scenarios. The Spray Master V350 designation targets spray-transfer processes at higher amperages, making it a practical choice for structural steel, heavy plate, and aluminum fabrication. The 25-foot cable length provides working room in tight or large-bay environments without excessive voltage drop. The Tweco rear connector interfaces with a wide range of industrial wire feeders commonly found in production welding cells.
