Tweco 1041-1120 Gasless Flux-cored Mig Gun 450 Amp 15 Ft

Product Description

The TWECO 1041-1120 is a 450-amp gasless flux-cored MIG gun designed for heavy-duty industrial welding applications. Built for use with all gasless (self-shielded) flux-cored wires, it delivers consistent arc performance without shielding gas. The gun features a 15-foot cable assembly with a rugged power cable constructed for abrasion and heat resistance. A micro-switch trigger design provides reliable start and stop wire feed control. Front-end consumables are heavy-duty rated and interchangeable with other leading flux-cored guns, reducing downtime when replacements are needed. Licensed welders and fabricators working in demanding production environments will find this gun suited for sustained, high-output work.

The 1041-1120 is suited for shipyards, offshore fabrication facilities, steel industry operations, repair and maintenance shops, and general industrial and automotive fabrication. The one-piece handle design allows the trigger to be positioned at the top or bottom of the handle, accommodating different welding positions and operator preferences. The replaceable conduit and four spare trigger lead wires stored within the cable assembly support field serviceability during extended use.
