PRINCIPLES OF GAP WELDING
The
CIR-KIT WELD 450
employs a closed loop system that 'looks' at the weld as it is taking
place, and modifies the power output accordingly. This loop is essential as during the weld
the temperature rises and the resistance of the workpiece also rises, causing the heat to be
automatically reduced.
