R-Tech C-MIG 315 Operation Instructions Manual page 5

Transport – Unloading
Never underestimate the weight of equipment, never move or leave suspended in the air above
people. Use recommended lifting equipment at all times.
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 fro proper grounding
methods.
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
