weld total thicknesses up to 1/4 in (6.3 mm). Not recommended for aluminum or copper alloys.
The Power of Blue®.
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 Order tongs/tips separately to match your applications
Set-up/weld switch permits checking of tong pressure and alignment without making a weld.
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.
Air filter/regulator assembly included.
Rated Output 20 kVA at 40% duty cycle depending on model, based on 10-second time period
Weight SSW 170 – 185 lb (77 – 84 kg) Depending on model
SSW foot switch permits user to use both hands to position weldment between tongs. Can be held longer if longer hold time is desired.
All spot welders operate on single-phase input power, and require an air supply of 60 PSI (414 kPa) minimum.
Adjustable tong pressure nuts to adjust tong pressure for different thicknesses and applications.
Power switch/power “on” light/circuit breaker protects control circuitry. Easy reset.
Cam-operated locking device simplifies installation and adjustment of bottom tong.
Ten-step current control adjusts output current with no change in duty cycle.
