5. Properly install and ground this equipment according to national, state, and local codes.
6. Turn off all equipment when not in use. Disconnect power to equipment if it will be left
unattended or out of service.
7. Use fully insulated electrode holders. Never dip the holder in water to cool it or lay it down on
the ground or the work surface. Do not touch holders connected to two welding machines at the
same time or touch other people with the holder or electrode.
8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Connect work piece to a good electrical ground.
11. Do not touch the electrode while in contact with the work (ground) circuit.
12. Use only well-maintained equipment. Repair or replace damaged parts as soon as practical.
13. In confined spaces or damp locations, do not use a welder with AC output unless equipped with a
voltage reducer.
Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and

WARNING! Welding produces fumes and gases. Breathing these fumes and
gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use an exhaust at the arc to remove welding fumes and gases.
3. If ventilation is poor, use an approved supplied-air respirator (PAPR).
4. Read the Safety Data Sheets (SDS) and the manufacturer’s instruction for the metals,
