MSW & LMSW Spot Welders, Air Cooled

The MSW and LMSW Series are lightweight, air-cooled units that are portable, easy to operate, and provide a quick and effective means for spot welding mild, galvanized or stainless materials. MSW models weld up to 1/8 in (3.2 mm) total material thickness or two pieces of 20 gauge (1.8 mm) galvanized metal. LMSW Models weld up to 3/16 in (4.8 mm) total material thickness or two pieces of 16 gauge (3 mm) galvanized metal. "T" models include a timer panel with a 0 to 5 second weld timer and power on/off switch, and come with a 10ft. (3m) input power cord and 10ft. (3m)interconnecting cord. The timer panel can be mounted on the optional SWP-2 pedestal, or any other convenient location. Hand lever locks tongs firmly on material, ensuring positive, accurate fit-up. Accommodates a wide variety of tongs and tips. Quick and easy adjustment for material thickness. Reversible for left- or right-hand operation.

Note: Tongs and tips must be ordered separately. One standard set of tips is supplied with each set of tongs.
