INSTALLATION
2. Keep the work and electrode leads as short
as possible and as close together as
possible.
Lengths should not exceed 7.6m. Tape the
electrode and work leads together into one
bundle when practical.
3. Be sure the torch and work cable rubber
coverings are free of cuts and cracks that
allow high frequency leakage. Cables with
high natural rubber content better resist high
frequency leakage than neoprene and other
synthetic rubber insulated cables.
4. Keep the torch in good repair and all
connections tight to reduce high frequency
leakage.
5. The work terminal must be connected to a
ground within ten feet of the welder, using
one of the following methods.
a) A metal underground water pipe in direct
contact with the earth for ten feet or more.
b) A 3/4" (19mm) galvanized pipe or a 5/8"
(16mm) solid galvanized iron, steel or
copper rod driven at least eight feet into the
ground.
The ground should be securely made and the
grounding cable should be as short as possible
using cable of the same size as the work cable,
or larger. Grounding to the building frame
electrical conduit or a long pipe system can
result in re-radiation, effectively making these
members radiating antennas.
6. Keep all panels securely in place.
7. All electrical conductors within 50 ft (15.2m)
of the welder should be enclosed in
grounded, rigid metallic conduit or
equivalent shielding. Flexible metallic
conduit is generally not suitable.
8. When the welder is enclosed in a metal
building, several earth driven electrical
grounds connected (as in 5b above) around
the periphery of the building are
recommended.
Failure to observe these recommended
installation procedures can cause radio or TV
interference problems.
Input Connections
Be sure the voltage, phase, and frequency of the
input power is as specified on the rating plate,
located on the machine.
WARNING
ELECTRIC SHOCK can kill.
SIGNIFICANT DC VOLTAGE is
present after removal of input
power.
DO NOT TOUCH live electrical parts.
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
The IM-MMA130-IWK Welder requires a 230V
50Hz supply.
Connect wires according to national coding.
Brown wire – Live
Blue wire – Neutral
Green/Yellow Wire – Earth (Ground)
