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. (152 mm) 12 in. (305 mm) 18 in. (457 mm) *Combined thickness uncoated mild steel using 6-inch (152 mm) tongs. **Duty cycle based on 10-second time period. (40% duty cycle means unit can weld for 4 seconds out of each 10-second time period.)
