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.
