Tweco 1048-1250 Mig Welding Gun 450A 10 Ft Miller Style

Product Description

The TWECO 1048-1250 is an air-cooled MIG welding gun rated at 450 amps with a 10-foot power cable and a Miller-style rear connection. Designed for demanding shop and production environments, this gun features a three-layer articulating conductor tube constructed from a copper tube, silicon resin fiberglass insulator, and a durable metal jacket. It accommodates wire sizes from 0.045 inches up to 1/16 inch and delivers a 60% duty cycle when used with CO2 gas. The cam-style, no-thread contact tip interface provides increased surface contact and extended consumable life. Licensed welding professionals and skilled maintenance technicians are the primary installers and operators of this equipment.

The 1048-1250 suits a wide range of welding applications including spray transfer and pulse welding modes using straight CO2 or mixed shielding gases. It is well suited for farm shops, maintenance and repair facilities, artistic metalworking, garage fabrication, and general production work. The fully insulated Mig-Kwik connection allows fast connect and disconnect at the wire feeder without removing the conduit. The 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced rapidly in the field.
