Preventive Measures

• E

nvironment

• The machine can be performed in an environment where conditions are dry with a dampness level of max 90%.

• Ambient temperature is between -10 to 40 degrees centigrade.

• Avoid welding under direct sun or wet/dripping conditions.

• Do not use the machine in an environment where conditions are polluted with conductive dust in the air or corrosiveness gas on the air.

• Avoid gas welding in the environment of strong airflow.

Safety Norms

•

The cutting machine has been installed with a protection circuit of over voltage, over current and overheating. When voltage and output current

and temperature of machine have exceeded the rate standard, welding machine will stop working automatically. Because that will be damage to

welding machine, user must pay attention to the following notice.

• The working area is adequately ventilated

• The cutting machine is powerful machine, when it is being operated, it is generated by high currents, and natural wind will not satisfy machine

cool demands. So, there is a fan in inner machine to cool down machine. Make sure the intake is not in block or covered, it is 0.3 meter from

welding machine to objects of environment. User should make sure the working area is adequately ventilated. It is important for the

performance and the longevity of the machine.

• Do not overload

• The operator should remember to watch the max duty current (Response to the selected duty cycle). Keep welding current is not exceed max

duty cycle current. Over-load current will damage and burn up machine.

• No over voltage

• Power voltage can be found in diagram of main technical data. Automatic compensation circuit of voltage will assure that welding current kept

in allowable arrangement. If power voltage is exceeding allowance arrangement limited, it will damage the components of machine. The

operator should understand the situation and take preventive measures.

• There is a grounding screw behind welding machine, with grounding marker on it. Mantle must be grounded reliable with cable which section is

over 6 square millimetres to prevent from static electricity and leaking.

• If welding time is exceeded duty cycle limited, welding machine will stop working for protection. If the machine is overheated, temperature control

switch is on “ON” position and the indicator light is red. In this situation, you don't have to pull the plug, in order to let the fan cool the machine.

When the indicator light is off, and the temperature goes down to the standard, so it can weld again.

Installation

General

The plasma cutter is equipped with a power voltage compensation equipment. When the power voltage

fluctuates between ±15% of rated voltage, it can still work normally.

When the machine is used with long cables, to prevent the voltage form going down, a bigger section cable is

recommended. If cable is too long, it may affect the performance of the power system. Thus, it is recommended

that you use a configured cable length.

1. Make sure the intake of the machine isn’t blocked or covered to avoid malfunctioning the system.

2. Use the cable (section not less than 6mm) to connect the housing and the ground. The way is from the

connecting screw in the back of the power source, or make sure it is grounded firmly. For safety, both ways

cab be used.

3. Use a pressure-resisting air pipe to connect the air intake and compressed air source and use a hoop and

other ways to tighten the joint. Air source should supply suitable pressure flow and should be dry. If your air

source does not meet the above requirements, you should consider using sole compressor of the right

power and air-decompressing filter, to supply suitable pressure and eliminate impurities and moisture from

the air.

4. Install the air-electricity system plug to the socket in the panel and secure it clockwise. Air plug of the cutting

torch and arc-keeping cable should be connected to the relevant socket, and secure with a screw.

5. Put the loop cable plug to the fastening socket, and tighten clockwise, another terminal will hold the work

piece.

6. As per input voltage grade, connect a power supply box of relevant voltage grade. Make sure there is no

errors and make sure the voltage is different among the permission rang.

7. Connect the cable as the example image shown, then you can start cutting.

Air Regulator Installation and Operation

1. Firmly tighten and seal the copper air hole at the IN and OUT terminal with a high-pressure rubber tube

firmly.

2. Tighten and seal the meter with a meter face rubber tube.

3. Secure the connecting shelf with a screw as the regulator position.

4. Remove the plastic screw and fix the regulator on the shelf.

5. Turn on the air valve, then turn up the pressure adjusting knob. Turn the pressure to rated volume (meter

inside shows Kgf/cm2), and then turn down the knob (+ means increasing pressure, - means decreasing

pressure).

6. If water in the gas filtering bottle is too much, please turn on the water valve to release the excess water.

CUT40 Mk III Plasma Cutter with Air Compressor

Operation

1. Turn on the power switch at the front panel, ensuring that the power switch is in the “ON” position. The time

indicator of the power switch is on.

2. Adjust the gas pressure to be adequate to the machine, then turn on the valve of the compressed air.

3. Press the control knob of the torch, the electromagnetic valve will start. The sound of HF arc-striking can be

heard, and the torch burner should flow out gas (burner of arc-supporting cutter should spurt fire).

4. Give about 1mm from the copper tip to work piece (further if it is arc-supporting cutter), then press the torch

knob and burn and strike arc, sparks of HF arc-striking will diminish immediately. Welding machine can

begin to cut.

NOTE: To let the plasma cutting machine to reach its best capacity and result, current and air pressure must be

matched well. Thus, when the current is set, the pressure and flow must be adjusted suitably. If the air flow is too

big and the cooling effect is too strong, it will cause an arc pause, and if the air flow is too small, the nozzle and

electrode will be too hot and burnt out.

Maintenance

WARNING! Power must be turned off for all checking and maintenance, before opening the housing,

make sure the power plug is disconnected.

WARNING! Blind experiments and careless repair may lead to more problems of the machine that will

make formal check and repair more difficult. When the machine is electrified, the bare parts contain life-

threatening voltage. Any direct and indirect contact will cause electric shocks, and severe electric shock

can lead to death.

•

Remove dust by dry and clean compressed air regularly, if welding machine is operating in environment

where is polluted with smokes and pollution air, the machine need removing dust every month.

•

Pressure of compressed air must be inside the reasonable arrangement to prevent damaging to small

components of inner machine.

•

Check internal circuit of welding machine regularly and make sure the cable circuit is connected correctly

and connectors are connected tightly (especially insert connector and components). If scale and loose are

found, please give a good polish to them, then connect them again tightly.

•

Avoid water and steam from entering the inner-machine, if they enter the machine, please dry inner-machine

then check insulation of machine.

•

If welding machine will not be operated long time, it must be put into packing box and stored in dry

environment.

CUT40 Mk III Plasma Cutter with Air Compressor

Troubleshooting

General

Fittings, welding materials, environment factor, supply powers may have something to do with welding. User

must try to improve the level of the welding environment.

Cutting surface is rough, poor cutting result

The machine may be not well operated. You can check it as follow:

•

Make sure the compressed air supply has enough pressure which is not less than 0.3MPa (3Kg/cm

2

), and its

range is ±0.05Mpa.

•

Electrode and nozzle are not matched with current. Check as follow:

Current 10-30A 30-40A 60-100A 100-120A

Nozzle φ1.0mm φ1.2mm φ1.3mm φ1.4mm

Arc-striking is difficult and easy to pause

•

Make sure quality of tungsten electrode is high.

•

Cutting current is too small and air flow is too big. And if cooling effect is too strong, it will lead to arc pause.

•

Power net voltage is low and input cable is too long.

Output current is not up to the rated value

When power voltage departs from the rated value, it will make the output current not matched with rated value;

When voltage is lower than rated value, the max output may be also lower than rated value.

Current is not stabilizing when machine is operating

It has something to do with factors as following:

•

Electric wire net voltage has been changed.

•

There is harmful interference from electric wire net or other equipment.

Electrode or nozzle burnt often

•

Current is too big, or nozzle is too small.

•

Air pressure is low and cooling effect is weak and nozzle is too hot.

Arc cannot cut into the steel plate fully, or too much spatter.

•

Maybe the machine capacity cannot meet the demand of that thickness, please use a bigger machine.

•

Electrode or nozzle is burnt, please change it.

NOTE: For normal operation, you should cut from the edge of the work piece, in this way you can protect the

torch from damage by spatter conglutination.
