PROBLEM
CAUSE
REMEDY
GENERAL OPERATION
No Power
Switch on rear is off
Turn on by moving switch to up position
Power supply
Test supply with another product, avoid using
extension leads.
Circuit breaker tripped
Check the rating of the curcuit breaker on the supply
and other appliances conencted to the circuit.
The welder is a high power device and it is
recommended that is be the only appliance on the
circuit to ensure it has enough power to operate.
Difficulty starting arc
Incorrect settings, cable connection
Check Arc/TIG switch is in correct postion.
Check earth and eletrode cables are in correct
terminals. Check cable conenctions to welder are
secure, rotate clockwise until firm.
Earth clamp conenction not adequate
Check earth clamp has good connection to material
being welded. Surface for clamp conenction needs
to be bare metal, remove rust or paint.
Welding technique
Hold electrode at correct angle, practice on scrap
material
Welder cuts out
Thermal overload active
The thermal overload light on the front panel will
be on and the welder will not operate until cooled
down and the light goes out. This is normal in heavy
welding, allow the welder to cool down.
ARC WELDING
Poor welding
Incorrect or wet welding electrodes
Select electrode type to suit material, electrodes
need to be dry.
Sticking welding
electrode
Settings
Increase current to recommended
Material
Clean area being welded to bare metal
Electrode type and size
Check the electrode type and size is appropriate for
the material being used.
Electrode damage
Replace with new welding rod
Welding current setting too high
Excessive welding
electrode consumption
Reduce welding current
Electrode size to small for material
Change to larger electrode
TIG WELDING
Poor welding
Eletrode tip damaged
Grind tip t point. Raplce with new TIG electrode
Gas supply
Check the correct shield gas is being used. Check
gas supply connections and flow settings.
Sticking electrode
Settings
Check welder TIG settings
Technique
TIG welding requires skill and practice, seek
assistance from experienced welder.
