3  Check that gun cable liner is not too 

short and is fitted correctly.  Refer 
wirefeeder manual for fitting instructions.

Constant poor arc characteristics

Check that the:

1  Correct polarity has been selected for 

work and weld cables

2  Shielding gas is correct for the 

consumable wire in use

3  Welding circuit is making good electrical 

connection. Ensure that the work clamp 
is securely tightened onto the work piece 
so that good electrical contact is achieved

4  All connections in the external welding 

circuit are clean and tight. Problems may 
show as hot spots

5  Work piece surface is not contaminated. 

Water, oil, grease, galvanising, paint, 
or oxide layers can severely disturb the 
welding arc and result in a poor weld.  

Porosity in weld caused by lack of 
shielding gas

1  Check that the correct gas flow rate has 

been set

2  Check for leaks in the gas hose. Replace 

if leaking

3  Check for leaks in gun/cable assembly, 

eg. fractured gas hose, broken or missing 
‘O’ rings.  Replace as required

4  Check the gun nozzle is free from spatter 

and is firmly attached to the welding gun 
to ensure that no air is being drawn into 
the shielded area. 

10 Service Information

Before removing the equipment 
cover, ENSURE that the equipment 
is disconnected from the mains 
power supply. When the equipment 
is energised LETHAL VOLTAGES are 
present on the electrical components 
enclosed.

The following information is intended 
for use by qualified service personnel. 
When the unit is energised LETHAL 
VOLTAGES are present on the electrical 
and electronic components. It is not 
intended that persons without suitable 
training and knowledge attempt 
to perform service tasks on the
