The current is AC. Since the capacitor current is out of phase with the inductive current, power factor correction will reduce the current. There really is no start up surge with welders. Light bulbs have a start up surge as the resistance of a hot filament in much higher than the resistance when the filament is cold.

Inverter style welders have a start-up surge, when the supply capacitors are charged at first plug-in or turn-on.
Certainly the typical buzz box would not have a start-up surge.
Enjoy, DoN.
do you know the Mfd value of the capacitor and how many are required? thanks
