Portable Resistance Spot Welders These lightweight, air-cooled units are portable, easy to operate, and provide a quick and effective means for spot welding mild, galvanized or stainless materials. These units are an excellent choice for maintenance work, and for spot welding applications that require portability and lower amperage welding. The 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. The 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 10 ft (3 m) input power cord and 10 ft (3 m) interconnecting cord. The Timer Panel can be mounted on the optional SWP-2 pedestal, or any other convenient location.
