Safety
All maintenance and checking should be carry out after the power is
completely cut off. Make sure the power plug of the machine is pulled out
before uncovering the welding machine.
When the machine is powered on, keep hands, hair and tools away from the
moving parts such as the fan to avoid personal injury or machine damage.
Periodic check
Check periodically whether inner circuit connection is in good condition
(esp. plugs). Tighten the loose connection. If there is oxidization, remove it
with sandpaper and then reconnect.
Check periodically whether the insulating layer of all cables is in good
condition. If there is any dilapidation, rewrap it or replace it.
Beware of static
In order to protect the semiconductor components and PCBs from the static
damage, please wear antistatic device or touch the metal part of the
enclosure to remove static in advance before contacting the conductors and
PCBs of the machine internal wiring.
Keep it dry
Avoid rain, water and vapor infiltrating the machine. If there is, dry it and
check the insulation of the welding machine (including that between the
connections and that between the connection and the enclosure) with an
ohmmeter. Only when there are no abnormal phenomena anymore, can the
machine be used.
Put the machine into the original packing in dry location if it is not to be
used for a long time.
Pay attention to maintenance
Periodic check should be carried out to ensure the long-term normal use of
the machine. Be careful when doing the periodic check, including the
inspection and cleaning of the machine interior.
Generally, periodic check should be carried out every 6 months, and it
should be carried out every 3 months if the welding environment is dusty or
with heavy oily smoke.
