1.3 Disconnect input plug or power before working on
machine.
2 Breathing welding fumes can be hazardous to your
health.
2.1 Keep your head out of fumes.
2.2 Use forced ventilation or local exhaust to remove
fumes.
2.3 Use ventilating fan to remove fumes.
3 Welding sparks can cause explosion or fire.
3.1 Keep flammable materials away from welding.
3.2 Welding sparks can cause fires. Have a fire extingui-
sher nearby and have a watchperson ready to use it.
3.3 Do not weld on drums or any closed containers.
4 Arc rays can burn eyes and injure skin.
4.1 Wear hat and safety glasses. Use ear protection and
button shirt collar. Use welding helmet with correct
shade of filter. Wear complete body protection.
