Periodic Inspection
Safety Warning
1.
To ensure safety, regular checks should be performed by professionals.
2.
Regular check can only be performed after turning off the power of the user distribution box and the welder (Visual
inspection which does not require contacting the conductor is excluded) to avoid electric shock, burns and other personal
injury accidents.
3.
Due to the capacitance discharge, checks should be carried out 5 minutes after the welder is powered off.
Operating Instructions
1.
In order to avoid the semiconductor components and circuit board from electrostatic damage, please
wear anti-static device before contacting the conductor and circuit board wiring within the machine, or
eliminate static electricity via touching the metal part of the casing.
2.
Please do not use any solvents other than neutral detergents for household application while cleaning
plastic parts.
Periodic Inspection Plan
1.
Periodic inspection must be performed to ensure the long-term and normal use of the equipment.
2.
Regular check should be performed in detail, including internal checking and cleaning of the
equipment.
3.
Generally, regular check is conducted once per every six months. But if the welding spot is dusty, or
with heavy oily smoke, regular check internal should be shortened to three months.
4.
The recommended periodic checking schedule is as shown in Table6-4.

Periodic Inspection Contents
(Except for the following items, the user can add inspection items according to the actual situation)
1.
Dust Removal within the Welder.
Remove the welder cover and side panel. Dry compressed air can be used to remove the spatter and dust
accumulated within the welder. And then clean the dirt and foreign matter which can hardly be removed by
purging.
Attention
If too much dust is accumulated on the radiator, heat dissipation will be affected which is prone to causing over-temperature
protection.
2.
Welding MachineInspection
Remove the top cover and side panel of the welder. Check whether the welder has any peculiar smell,
discoloration and over-temperature damage. Check whether the connection part is loosened.
3.
Cable and Gas Pipe Checking
Beside daily check, cable, gas pipe, safety ground wire etc. should be further checked in detail and apply
routine supplementary fastening.Withstanding voltage test and insulation test Withstanding voltage test
and insulation test should be carried out by the after-sales service personnel of our company or personnel
with professional knowledge of electrical and welding machine.
1.
Turn off the power distribution box.
2.
Remove all safety grounding wires on the casing.
3.
Connect the three input power cords (not including the yellow green one) to make it short circuit.
4.
Turn the welder power switch to "ON".
