Electrical Installation 

WARNING! 

 ELECTRIC SHOCK CAN KILL 

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  
 

4.  Keep earth lead connection to work in good condition – Clean area on workbench where 

earth clamp is situated on a regular basis. 

Input Connections 
 

Make sure the voltage, phase and frequency of input power is as specified on machine rating plate 
located at rear of machine. 
 
Have a qualified electrician provide suitable input power as per national electrical codes. Make sure 
machine is earthed / grounded.
