Notice:
Entry of splash and iron powder caused in welding and polishing into the
inside of power, will lead to the deterioration of insulation. To avoid the fire
caused by the deterioration of the power's insulation, please obey the rules:
1. Please separate the welding power from the operation of welding and polishing.
2. Please maintain and repair regularly to avoid the deterioration of the insulation
caused by the pilling of dust.
3. When splashed iron powder into the inside of power, please turn off the switch of
welder power and distributor box, then blow it clean by air.
Notice:
In order to prolong the service life of the machine, please pay careful attention
to its upkeep and repair. Please maintain the welder once at least every six
months as stated below. The power of distributor box and welder must be
switched off.
1. Use resistance instrument to measure the resistance between ground and the
primary winding. Secondary winding, and each other winding. And the resistance
should be more than 1MΩ.
2. Winding over-heated. You need use compressed air to blow the dust in the
winding and other parts away.
3. Examine the contact state of power switch. If it is burnt on the surface, it should be
changed.
4. Examine whether the bolt and nut is tightly fixed. If they are loose, you need to
screw it tightly.
5. When the machine needs to be repaired, please inform the distributor with the
model and product number as soon as possible.
Notice:
1. Please confirm the rated specifications and then make use of it.
2. Avoid over-load usage.
2a. Serious over-load can burn machine and shorten the service life.
2b. Over-load may cause noise and make the rotation of hand-wheel difficult.
3. The connection of cable and terminal of machine should be steady. Or it will cause
local running hot to burn the terminal and cable.
4. A too long output cable will lead to impediment current circulation and cause
electric power loss. If the surface insulation of cable is soiled, the arc will be
unstable. So you need to change the old cable in time.
5. The power must be switched off after operation.
6. The internal movable iron-core sleek structure has been adjusted well. Do not
move it unnecessarily.
7. Place the welder in the shade. Do not keep the machine in the sun for a long time.
