SSW Series Spot Welders Applications Quick Specs Sheet Metal Work Light Fabrication Maintenance Work Water-Cooled Resistance Spot Welders Resistance Spot Welding Rated Output Work Capacity 20 kVA units weld total thicknesses up to 1/4 inch (6.3 mm). Not recommended for aluminum or copper alloys. 20 kVA at 40% duty cycle depending on model, based on 10-second time period SSW foot switch permits user to use both hands to position weldment between tongs. Can be held longer if longer hold time is desired. SSW models are designed for stationary use and come with an all-steel pedestal which houses timers and controls. SSW models come complete with: Stationary welding head Remote foot switch Pedestal inclusive of controls and timer Air filter/regulator assembly All spot welders operate on single-phase input power, and require a minimum air supply of 60 PSI (414 kPa). Adjustable tong pressure nuts to adjust tong pressure for different thicknesses and applications. Note: Order tongs/tips separately to match your applications Power switch/power “on” light/circuit breaker protects control circuitry. Easy reset. Air filter/regulator assembly included. Cam-operated locking device simplifies installation and adjustment of bottom tong. Set-up/weld switch permits checking of tong pressure and alignment without making a weld. Ten-step current control adjusts output current with no change in duty cycle. Built-in squeeze/weld timer makes it quick and easy to set or adjust squeeze and/or weld time in hundredths of a second. LED display makes it easy to read and see timer settings. (Subject to change without notice.) Stationary Model Work Capacity* Rated Output** Rated Output (Calibrated w/ standard-type tongs) 6 in.

Tongs and Tips (Must be ordered separately from spot welders. One pair of tips are supplied with each set of tongs.) Tong Length 6 in. 12 in. 18 in. (150 mm) (304 mm) (457 mm) Notes for tongs and tips: Tips Included No. 1 Morse Taper No. 2 Morse Taper Tongs and tips shown to the left can be used with all PSW and SSW model spot welders. Recommended maximum tong length is 18 inches (457 mm). Tong throat-height dimension for standard 90° and 45° tongs is 4-1/4 inches (108 mm). Throat length is measured from the center of the spot tips to the front water hose connection. X = tong length. One set...
