Replace all weld lead spliced within lO feet of the holder. To reduce the chance of shock, check the electrode holders for loose or exposed connection. Never coil or loop electrode cable around any part of your body. Never use pipelines carrying gases or flammable liquids or conduits carrying electrical conductors as grounds. Don't ground to a building structure that is a great distance from the weld.
Wet floors are dangerous and can cause electrical shock.
Special precautions must be taken. Make sure the insulation is sufficient on higher open-circuit voltage. Do not change the polarity switch when your machine is under load. Arcing because of high current can burn the switch contact surface and can seriously burn you. This switch shuts down the machine immediately in an emergency.
