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
Always service a PC board on a static-dissipative surface, while
wearing a grounded wrist strap.
