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.
Ten-step current control adjusts output current
with no change in duty cycle.
Cam-operated locking device simplifies
installation and adjustment of bottom tong.
Power switch/power “on” light/circuit breaker
protects control circuitry. Easy reset.
