Tweco 1040-1888 VELOCITY2 Supra Xt Mig Gun 400A 15ft

Product Description

The TWECO 1040-1888 is a heavy-duty MIG welding gun rated at 400 amps, designed for demanding industrial and fabrication welding environments. Part of the VELOCITY2 SUPRA XT VSEHD line, this gun handles wire up to 1/16 inch and ships with a 15-foot cable assembly. The three-layer conductor tube construction — copper tube, silicon-resin glass insulator, and metal jacket — threads directly into the front block for improved electrical conductivity and heat management. A micro-switch trigger design provides reliable start and stop wire feed control. Licensed welding professionals and industrial MIG operators are the primary installers and users of this equipment.

This gun is built for high-output MIG applications including spray transfer mode and pulse welding using straight CO2 or mixed shielding gases. Typical deployment spans automotive body and frame shops, steel fabrication facilities, shipbuilding and offshore yards, and repair and maintenance operations. The heavy-duty rating makes it appropriate for continuous or near-continuous duty cycles in production environments. Industrial and general fabrication shops that require consistent arc performance at elevated amperage will find this gun suited to those demands.

Key Features

• 400-amp rating supports spray transfer and pulse welding modes
• Accepts wire up to 1/16 inch diameter

Compatibility

Designed as an OEM-style heavy-duty MIG gun for use in 400-amp-class wire feed welding systems requiring a 15-foot cable assembly and wire sizes up to 1/16 inch.

Installation Notes

Installation and service of MIG welding guns should be performed by a qualified welder or welding equipment technician. Power down and disconnect the wire feeder and welding power source before making any cable or connection changes. Ensure shielding gas supply is shut off before disconnecting the gas line. Follow the equipment manufacturer's guidelines and applicable AWS safety standards during setup and service.
