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
in cutting.Torch should be inclined and it is 1mm 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 can
be operated.
5.If the machine will not be used long time , it should be put in its own
packing box and store in
dry environment.
