• Only use appropriate sized torch cables
(length and capacity). The recommended
total combined length of the torch and work
cable is 50 feet.
• Torch and work cable should not be "coiled"
during welding operations.
• Maintain the duty cycle of the power supply.
Refer to section 3.8 for the recommended
duty cycle.
b) Replace PCB6 (WK-5549)
• Refer to section 12.3.6 for the replacement of
PCB6.
