WARNING General Warning
Before servicing the welder, make sure to do the following:
1. Turn off the welder and unplug main power.
2. Turn air pressure to zero and disconnect your main air line connection.
Failure to do this leaves the welder under potentially dangerous air
pressure.
3. Wait approximately 2 minutes after unplugging the welder before touching
internal electrical components.
CAUTION General Warning
The welder contains static-sensitive printed circuit (PC) boards.
Irreversible damage can occur to these boards if they receive a static
discharge from tools or service personnel. To prevent damage to PC
boards:
1. Always service a PC board on a static-dissipative surface, while wearing a
properly grounded wrist strap. Follow the manufacturer’s instructions for
proper use of this equipment.
2. For ground points, refer to schematic diagrams in
Chapter 3: Schematics.
CAUTION General Warning
Take precautions not to leave any loose objects (such as screws,
bolts, nuts, and so forth) in the welder. If you drop an object into the
welder, retrieve the object immediately.
