Safety Precautions 

 

Read entire section before starting installation 

 

WARNING! 

 

 

Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input 
power at the fuse box before working on this equipment.

  

Do not touch electrically live parts. Always 

connect the machine to an earthed mains supply as per national recommended standards. 
 

 
Select suitable location 
 

Place the welder where clean cooling air can freely circulate in and out of the front & rear louver 
vents. Dirt, dust or any foreign material that can be drawn through vents into welder must be kept to 
a minimum. Failure to observe these precautions can result in excessive operating temperatures 
which can lead to plant failure. 
 

Grinding 

 
Do not direct grinding particles towards the welder. An abundance of conductive material can cause 
plant failure. 

 
Stacking 
 

This machine cannot be stacked. 
 

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 IP23S 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.
