5.Pilot arc current adjustment
The PLW 402 pilot arc current is factory set for PT-300 and PT-8 to 10 A. If PT-75 or PT-150 resp.
PTM-150 are used, pilot current must be reduced to 5A. This is performed by eliminating jumper at
resistor R105.
The PLW 202 pilot arc current is factory set to 5A and can be increased to 10A by connecting
jumper at resistor R105.
Disconnect machine from mains before opening the machine!
