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.
