WARNING!
ELECTRIC SHOCK CAN KILL
Machine grounding and High Frequency Interference Protection
This welder must be grounded to earth
The high frequency generator being similar to a radio transmitter may cause
interference to radio, TV and other electronic equipment. These problems may be
the result of radiated interference. Proper grounding methods can reduce or
eliminate this.
Radiated interference can develop in the following ways
1. Direct interference from welder power source
2. Direct interference from the welding leads
3. Direct interference radiated from feedback into power lines
4. Interference from re-radiation by un-grounded metallic objects
Keeping these contributing factors in mind, installing equipment as per following
instructions should minimize problems
1. Keep the welder input power lines as short as possible and enclose as much of
them as possible in metal conduit or equivalent shielding. There should be a good
electrical contact between this conduit and ground (Earth)
2. Keep the work and electrode leads as short as possible. Tape the leads
together where practical
3. Be sure the torch and earth leads rubber coverings are free from cuts and
cracks that allow welding power leakage
4. Keep earth lead connection to work in good condition – Clean area on
workbench where earth clamp is situated on a regular basis.
