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.
Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers
smaller than recommended will result in ‘nuisance’ shut off from welder inrush currents even if
welding at low amperages.
Failure to follow these instructions can cause immediate failure within the welder and void
machines warranty.
Turn the input power OFF at the mains switch & fuse box before working on this equipment.
Have a qualified electrician install & service this equipment.
Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before
working inside this equipment. Do not touch electrically live parts

a 16A supply for Tig operation and 23A for MMA welding. It comes with a 2.5 metre mains cable
attached.
Connect wires according to national coding.
Brown wire – Live
Blue wire – Neutral
Green/Yellow Wire – Earth (Ground)
