TIG Torches & MIG Guns

TIG torches and MIG guns deliver current, shielding gas and, for MIG, the wire to the arc, so their condition and specification directly affect weld quality and arc stability. For TIG, key points are rated current, air or water cooling, flexible or rigid head, gas lens versus standard collet body, and the tungsten type and diameter. Water-cooled torches are used for continuous high-current welding on pressure piping and in hot ambient conditions.

MIG guns are chosen by amperage rating, duty cycle, cooling type, neck angle and length, and the wire diameter and type, since a steel liner suits steel wire while a low-friction liner suits aluminium. Consumable parts such as contact tips, nozzles, diffusers and liners wear and should be replaced on schedule to avoid erratic feeding and porosity. Connector compatibility with the power source or feeder must be confirmed before ordering.

Seven Star LLC supplies torches and guns to match the machines it provides; send the machine model and application. They work with MIG/MAG welding machines, TIG welding machines and multi-process welding machines, and use wire from solid welding wire, flux-cored welding wire and TIG welding wire. Protect the welder with welding helmets and face protection. See all welding accessories and safety.
