Voltage automatic compensation circuit will prevent from exceeding allowable
arrange .If power voltage is too high, that will damaged to components. User must
be carefully.
4.
There is a grounding screw, which is marked grounding behind cutting machine.
Make sure the mantle is grounded reliably by cable whose section is 6 square
millimeter in order to prevent from leaking electrify and bringing electrostatic.
5. Inter heat-variable component is starting if machine is exceeded in duty cycles.
That will cause-cutting machine will stop working suddenly and inter red diode is
lit. User need not break the circuit and the fan may continue working in order to
cool down the machine. Once temperature is reduced to allowable arrange, machine
can be operated again.
CUTTING NOTES
1.
Make sure copper tip must not connect to work piece directly when user is cutting.
Torch should be inclined and it is 1 mm from inter-hole of copper tip to work piece
in order to protect copper tip.
2.
As arc-supporting cutting machine, if arc-supporting frequency is down or there is
no arc supporting, user may be get rid of oxidized film of inter electrode by abrasive
paper. Then machine will be operated normally.
MAINTENANCE AND CHECK TROUBLE
Maintenance
1.
Remove dust by compressed air regularly .If cutting machine is placed in
environment where condition is polluted with smoke and dust, cutting machine must
be removed dust every day.
2.
Pressure is adequate to cutting in order to protect little components.
3.
Check the electrify connectors and make sure the connectors are connected firmly
(specially connect and insert components), tighten the connectors
4.
Avoid water into machine and machine become damp, or the machine must be dried
in time and measured insulation by meter. After there is no problem, the machine
