Seam Welding with Remote Enclosures
WTC welding controls provide a load resistor across the
welding transformer. This resistor assures proper SCR firing
and transient voltage suppression under all operating
conditions.
The load resistor supplied as standard equipment is designed
for spot welding or short duration seam welding use with a
maximum
weld time of 5 seconds and a maximum duty cycle
of 33%. If your welding application involves weld times longer
than 5 seconds per weld or an overall duty cycle exceeding
33%, a larger load resistor is required. Please contact the
factory or your sales representative to obtain the correct load
resistor for your application.
