®

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.
