Maintenance
Clean out the dust inside the power supply periodically: Too much dust inside the power supply would
reduce the insulation performance of the welding machine, which brings direct threat against machine
operation and personal safety. It should be cleaned at least twice a year. If welding environment with
heavy smoke and pollution, the machine should be cleaned daily. Before cleaning, turn off the power
switch, remove the side plate and top cover, and blow the dust with dry compressed air from top to
bottom. The pressure of compressed air should be at a proper level in order to avoid the small parts
inside the machine being damaged. If any grease, wipe with a cloth.
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 insulation covers of all cables is in good condition. If there is any
dilapidation, rewrap it or replace it.
Check the insulation resistance of the welding machine periodically: Mainly check the insulation
resistance between the welding machine power input and output and insulation resistance between the
power input and the enclosure, and make sure such insulation resistance should be greater than 10
ohms.
Put the machine into the original packing in dry location if it is not used for a long time.
The machine may be damaged during welding. Timely maintenance should be carried out after the
confirmation of damage. Only qualified individuals can uncover or repair the machine. Otherwise, further
machine fault and further damage to valuable parts may occur.
Ask professionals for help if any difficulty.
If any difficulty in installation or operation of the machine, please refer to the relevant contents in this manual.
If you can not fully understand after reading, or can not solve the problem according to the instructions in this manual,
please contact your supplier or our company for help.
Component explosion may cause injury.
When the inverter welder is powered on, invalid components may explode or lead to explosion of other components.
Wear face guard and long-sleeved clothing when maintaining the inverter welder.
Static causes damage to PCB.
Wear a grounded antistatic wristband when carrying PCBs and components.
Store, carry and transport PCBs with appropriate antistatic bags or boxes.
Electric shock may occur when testing.
Cut off the power supply of the welder before lead testing.
Test with an instrument with auto-fixing clamp on one of its leads.
Read the instructions of the testing equipment carefully.
