Miller Electric LMSW, MSW User Manual

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.
