welding equipment.
1.1 INSTALLATION OF EQUIPMENT

receptacle and wiring. If damaged, replace
immediately with approved electrical connec-
tions and adequately sized wiring.
3. Connect the welding ground as near as possi-
ble to the operating area.
4. Do not pass welding equipment cables
through or near lifting chains, crane cables or
any electrical lines.
5. If earth grounding of the workpiece is
required, ground it directly with a separate
cable.
6. Do not touch the electrode if you are in con-
tact with the work, ground or another elec-
trode from a different welding machine.
7. Use only well-maintained equipment. Repair
or replace damaged parts immediately.
