3 Installation
Input cable connection (enclose installing diagram)
1. Every machine has been disposed a power cable which must be connected to
coordinated voltage class in compliance according to input voltage of cutting machine .If
cutting machine whose power voltage is 110V or 220V is connected wrong to AC 380V,
that will cause components of inter-machine are burned up.
2. Make sure power cable is connected to power switch reliably and prevent from
oxidizing.
Make sure power voltage is inside the waved range.
Output cable connection
1. Make sure tube of pressed air is connected to copper connector by high-pressure
rubber tube firmly.
2. Make sure copper screw of another end of torch is connected to gas-electrify integration
terminal then tighten them clockwise relation (prevent from leaking gas). Mobile plug of
another end of earth cable is connected to positive terminal of front panel then tighten it.
3. Make sure air plug of torch is connected to switch connector of panel (If it is pilote-arc
cutter, pilote-arc cable of torch is connected to terminal of pilote-arc wiring column.)
CHECK
1. Check if cutting machine is grounded reliably according to standard.
2. Check if all connectors are connected firmly.
3. Check if power voltage is correct.
OPERATION
1. Plug in the plasma cutter, set the power switch to ON position. At this
time indicator of
Screen will show the current volume. Set the switch to SET AIR
2. Adjust the gas pressure and make it is adequate to machine, open the valve of pressed
air.
3. Make sure cutting current is adequate to machine according to thickness of cutting
piece.
power switch is on.
position. There will be constant air flow.

5 INSTRUCTION NOTES
5.1 Operation environment
1. The cutting machine can perform in environment where conditions are particularly
harsh and with outside temperature between –10 and +40 degrees centigrade with a
dampness level of max 80%.
2. Avoid using in sunshine and dropping environment.
3. Keep machine dry and avoid water into machine.
4. Do not use the cutting machine in environment where condition is polluted with high
concentration of dust or corrosive gas in the air.
5.2 SAFTY
1. Make sure the working area is adequately ventilated.
Cutting machine is light and its structure is compact and the electromagnetic fields
generated the high current .So natural wind is not satisfy to cool down components,
there are two axial-flow fan in inter-machine in order to force to cool down it.
NOTES: Exhaust shutter must not in block or covered, it is 0.3 m from machine to environment
objects. Make sure keep improving ventilated situation, it is very important to machine.
2. No over-load!
Limited to cutting current strictly according to max allowable current with all kinds of
duty cycles.
Do not exceed load working in order to prevent from shorting use lifetime of cutting
machine even burning up machine.
3. No over-voltage!
Power voltage range of cutting machine is according to main technical data sheet.
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
FORCECUT62i- 60AMPPlasmacutter 110v/220v

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.
5.3 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.
6 MAINTENANCE AND CHECK TROUBLE
6.1 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.
