Maintenance - Impax IM-MMA130-IWK Manual

MAINTENANCE

WARNING. ELECTRIC SHOCK can kill.
Have an electrician install and service this
equipment.
Turn the input power off at the fuse box,
disconnect supply lines and allow machine to sit
for five minutes minimum to allow the power
capacitors to discharge before working inside
this equipment.
Do not touch electrically hot parts.
WARNING. Do not open this machine and do
not introduce anything into its openings. Power
supply must be disconnected from the machine
before each maintenance and service. After
each repair, perform proper tests to ensure
safety.
CAUTION. The power supply must be
disconnected from the machine before each
maintenance and service. Always use gloves in
compliance with the safety standards.
Routine Maintenance
The welder must be kept clean and dry at all
times. Use a dry cloth to clean the welder.
Keep the electrodes clean and dry and ensure
all cables are in good condition.
Keep the louvre passages clean to avoid a build
up of dirt and oxides inside the machine, which
can reduce machine output.
The nozzle will occasionally need to be cleaned
of spatter from welding. Clean it with a metal
brush. When the nozzle deteriorates or can no
longer be cleaned, it will need to be replaced.
Unscrew the nozzle and replace it with a new
one.
Always try to avoid getting particles of metal
inside the machine since they could cause short
circuits.
Periodically clean the inside of the welder with
compressed air, ensuring you wear a mask
during the operation.
Caution: Water must never come into contact
with the welder.
Regularly check the general condition of the
tool. Check for loose screws, misalignment or
binding of moving parts, cracked or broken
parts, damaged electrical wiring, and any other
condition that may affect its safe operation.
If the supply cord requires replacing, the task
must be carried out by the manufacturer, the
manufacturer's agent, or an authorised service
centre to avoid a safety hazard.
Welding Mask Maintenance
Always maintain the welding mask in good
condition. If the clear glass protection lens
becomes badly pitted, sufficient to interfere with
vision, or cracked, have it replaced immediately.
NEVER use any dark filter lens other than that
provided by Impax, or one with the same
certified 'Optical class' (degree of protection).
The shield should always be cleaned with a
clean soft cloth after use, ensuring the lenses
are clean. Remove any dust that may have
accumulated and store it in a safe place where it
cannot be damaged.
NEVER use a shield that is not in perfect
condition.
