Miller Electric MSW User Manual
Msw and lmsw series, Options and accessories, 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.
