'Constant voltage' refers to the ability to fluctuate output current to maintain a set voltage. Constant voltage can be used for applications where the workpieces do not have flat surfaces, e.g. crossed wires, and where the resistance varies significantly, and for extremely short welds (less than 1 millisecond).
Constant voltage mode:
· Compensates for parts misplacement and force problems
· Reduces weld splash
· Is ideal for round (non-flat) parts
