Transport & Unloading
Never underestimate the weight of equipment, never move or leave suspended in the air above people. Always use
recommended lifting equipment.
WARNING!
Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above personnel.
Tilting
Machine must be placed on a secure level surface or on a recommended undercarriage/trolley. This machine may
topple over if this procedure is not followed.
Environmental Rating
The welding power source carries the IP21S rating. It may be used in normal industrial and commercial
environments. Avoid using in areas where water / rain is around.
Read and follow the Electric Shock Warnings in the safety section if welding must be performed under electrically
hazardous conditions such as welding in wet areas or water on the work piece.
Machine grounding and High Frequency Interference Protection
This welder must be grounded to earth. See national electrical codes for proper grounding methods.
The high frequency generator is like a radio transmitter and 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
•
Direct interference from welder power source
•
Direct interference from the welding leads
•
Direct interference radiated from feedback into power lines
•
Interference from re-radiation by un-grounded metallic objects.
Keeping these contributing factors in mind, installing equipment as per following instructions should minimize problems.
•
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).
•
Keep the work and electrode leads as short as possible. Tape the leads together where practical.
•
Be sure the torch and earth lead rubber coverings are free from cuts and cracks that allow welding power
leakage
•
Keep earth lead connection to work in good condition Clean area on workbench where earth clamp is
situated on a regular basis.
