12.Industrial applications must follow OSHA requirements.

13.Never plug the Power Cord of this product into an electrical outlet while standing on a wet or damp surface.

14.Connect the earth ground as near as possible to the operating area. Earth connections to structural parts of the building or other places distant to the operating area will reduce their effectiveness and increase the danger of electric shock.

15.In addition to grounding the workpiece with the Welder Grounding Clamp, an earth grounding of the workpiece is recommended. Ground it directly to an earth pipe or grounding rod with a separate cable of appropriate size. IMPORTANT: Only a qualified, certified electrician should perform this procedure.

16.Do not touch the welding wire if you are in contact with the workpiece, ground, or another welding wire from a different machine.

17.Do not allow the welding wire to touch earth ground. Accidental earth discharges may cause overheating and fire hazards.

18.Do not pass equipment cables through or near lifting chains, crane cables, or any electrical lines.

19.Never use the Welder near water. Ensure that the surrounding area and cutting objects are dry. Do not spray water or other liquids on or near the Welder.

20.Avoid all direct contact between the skin and wet garments and metal parts under electrical power. Check that gloves and protective clothing are dry.

21.Never leave the Welder unattended when it is plugged into an electrical outlet. Make sure to unplug it from its electrical outlet before leaving the area.

22.Do not unplug the Welder by pulling on the Power Cord. Keep the Power Cord away from heated surfaces.

23.Always turn off the Welder in the event of a power failure.

24.Significant DC electrical voltage exists after turning off and unplugging the Welder. Discharge the electrode to ground before handling.
