AIR N ARC 300 SERIES ALL-IN-ONE POWER SYSTEM SECTION 1: SAFETY
Do not work alone!
Disconnect input power or stop engine before installing
or servicing this equipment. Lockout/tag out input power
according to OSHA29 CFR1910.147 (see Section 1.9,
Principal Safety Standards).
Properly install and ground this equipment according to
its Owner's Manual and national, state, and local codes.
Always verify the supply ground: check and be sure that
input power cord ground wire is properly connected to
ground terminal in disconnect box or that cord plug is
connected to a properly grounded receptacle outlet.
When making input connections, attach proper grounding
conductor first and double-check connections.
Frequently inspect input power cord for damage or bare
wiring; replace cord immediately if damaged—bare
wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced
cables.
Do not drape cables over your body.
If earth grounding of the work piece is required, ground it
directly with a separate cable.
Do not touch electrode if you are in contact with the work,
ground, or another electrode from a different machine.
Use only well-maintained equipment. Repair or replace
damaged parts at once. Maintain unit according to
manual.
Do not touch electrode holders connected to two welding
machines at the same time since double open-circuit
voltage will be present.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to
work piece or work table as near the weld as practical.
Insulate work clamp when not connected to workpiece to
prevent contact with any metal object.
Do not connect more than one electrode or work cable to
any single weld output terminal.
