1.5 Functions and characteristics of the cutting machine

CUT series are inverter cutting machines made by our company with advanced inverter technology. They are more mature products with stable performance. With PWM technology and high power component MOSFET (or IGBT), it inverts the DC voltage, which is rectified from 50Hz/60Hz input AC voltage, to 30K~100KHz AC high voltage. Then the voltage is dropped and rectified to output the high power DC power supply for cutting. The machine adopts switching power supply inverter technology, greatly reducing the volume and weight of the cutter, and obviously enhancing the conversion efficiency by 30%.

Features of CUT series

Economic and practical by adopting compressed air as the plasma gas source. The cutting speed has increased by 1.8 times when compared with oxyacetylene cutting.

It can cut thick steel plate conveniently and quickly. It is easy to ignite arc, and post-flow function is available.

It has a wide range of use, especially for cutting stainless steel, copper, cast iron and aluminum, etc.

With simple operation and high cutting speed, smooth cutting surface can be obtained, and polishing is unnecessary.

It adopts HF arc ignition mode.

1.6 System characteristics

1) Duty cycle

Rated duty cycle refers to the percentage of the normal work time of the machine under rated maximum current holding in the period when taking 10 minutes as a period. The rated duty cycle of this machine is 40 -60%. Using the cutting machine continuously overrunning the rated load may lead to overheating of the machine, and frequently using the machine overrunning the rated load may accelerate the aging of the machine or even burn the machine.

2. INSTALLATION AND CONNECTION

2.1 Installation requirements

1) Connection of input cable

In order to ensure personal safety and avoid electric shock, please ground the machine reliably by connecting the ground wire (yellow-green wire) of the machine to the grounding device in the switching box.

A primary power supply cable is available for this cutting machine. Connect the power supply cable to the rated input power. The primary cable should be tightly connected to the correct socket to avoid oxidization. Check whether the voltage value varies in acceptable range with a multi-meter.

The cross section of the leads used in the switching box should meet the requirements of the maximum input capacity of the machine.

2) Connection of output cable

Connection of cutting torch

Connect the copper nut on the cutting torch to the gas-electric connector on the front panel of the machine, and tighten it clockwise to avoid gas leakage. Insert the quick plug on the work clamp into the “+” output terminal on the front panel of the machine, and tighten it clockwise.

Connection of the torch trigger

Insert the plug of the torch trigger on the cutting torch into the socket of torch trigger on the machine panel. (For models with pilot arc function, connect the pilot arc wire on the cutting torch to the terminal for pilot arc wire on the machine panel.) Install the electrode into the cutting torch by turning it slowly, and tighten it. Then, get the nozzle and protective sleeve installed in sequence.

Connection of earth cable

Insert the quick plug on the earth cable into the quick socket marked with “ ” at the bottom of the front panel of the machine, and tighten it clockwise. Clamp the workpiece with the work clamp at the other end of the earth cable.

2.2 Precautions

1) Make sure the place to install the machine can bear the weight of the cutting machine.

2) Do not install the machine at places where water droplet splash may be produced, such as near water pipes.

3) Cutting should be carried out in dry environment with humidity of 90% or less.

4) The temperature of the working environment should be between -10℃ and 40℃.

5) Avoid cutting in the open air unless sheltered from sunlight and rain. Keep it dry at all times and do not place it on wet ground or in puddles.

6) Avoid cutting in dusty area or environment with corrosive chemical gas.

7) Do not carry out cutting with the cutting machine placed on a platform with a pitch greater than 10°.

Overcurrent/overvoltage/overheating protection circuit is installed in this machine. When the mains voltage, output current or inner temperature exceeds the set standard, the machine will stop automatically. However, excessive use (e.g. too high voltage) of machine may also damage the machine, so please note:

This cutting machine can create powerful cutting current and has strict cooling requirements that cannot be met with natural ventilation. Therefore the built-in fan is very important in enabling the machine to work stable with effective cooling. The operator should make sure that the louvers be uncovered and unblocked. The minimum distance between the machine and nearby objects should be 25cm.

This machine is of automatic mains voltage compensation, which ensures that the cutting current varies within the given range. In case that the input mains voltage exceeds the tolerance value, it would possibly damage the machine. The operator should understand this circumstance fully and adopt relevant precautions.

Remember to observe the max load current at any moment (refer to the corresponding duty cycle). Make sure that the cutting current should not exceed the maximum load current. Overload could obviously shorten the machine's lifespan, or even damage the machine.

A sudden halt may occur with the yellow LED on the front panel on while the machine is of over-load status. Under this circumstance, it is unnecessary to restart the machine. Keep the built-in fan working to lower the temperature inside the machine. Cutting can be continued after the inner temperature falls into the standard range and the yellow LED is off.

3.4 Operation method

1) Turn on the power switch of the machine, and the power indicator illuminates.

2) Select proper working mode and proper function. There are two working modes available on the machine panel: 2T and 4T. There are two functions available: normal cutting and metal mesh cutting. The electrode and nozzle are more easily to wear out in metal mesh cutting.

3) Push the torch trigger on the cutting torch, the cutting machine works.

4) Set cutting current according to the thickness of workpiece.

5) Bring the copper nozzle of the cutting torch into contact with the workpiece (For models with pilot arc function, keep a distance of about 2mm between the copper nozzle of the torch and the workpiece.), and then push the torch trigger. After the arc is ignited and started, raise the cutting torch to the position about 1mm above the workpiece, and start cutting.

3.5 Notes for cutting operation

It is recommended not to ignite the arc in the air if not necessary, for it will shorten the lifespan of the electrode and nozzle of the torch.

It is recommended to initiate the cutting from the edge of workpiece, unless penetration is needed.

Ensure spatters fly from the bottom of workpiece while cutting. If spatters fly from the top of workpiece, it indicates that the workpiece can not be fully cut because the cutting torch is moved too fast or the cutting current is too low.

Keep the nozzle slightly touching the workpiece or keep a short distance between the nozzle and workpiece. If the torch is pressed against the workpiece, the nozzle may stick to the workpiece, and smooth cutting is unavailable.

For cutting round workpiece or to meet precise cutting requirement, molding board or other assistant tools are needed.

It is recommended to pull the cutting torch while cutting.

Keep the nozzle of cutting torch upright over the workpiece, and check if the arc is moving with the cutting line. If the space is not enough, don’t bend the cable too much, step on or press upon the cable to avoid suffocating of gas flow. The cutting torch may be burned because the gas flow is too small. Keep the cutting cable away from edge tools.

Clean up the spatters on the nozzle timely, for it will affect the cooling effect of the nozzle. Clean up the dust and spatters on the torch head after using everyday to ensure good cooling effect.

The workpiece is not cut fully. This may be caused by:

The cutting current is too low. The cutting speed is too high. The electrode and nozzle of the torch are burned. The workpiece is too thick.

Molten slag drops from the bottom of workpiece. This may be caused by:

The cutting speed is too low. The electrode and nozzle of the torch are burned. The cutting current is too high.

All maintenance and checking should be carry out after the power is completely cut off. Make sure the power plug of the machine is pulled out before uncovering the cutting machine. When the machine is powered on, keep hands, hair and tools away from the moving parts such as the fan to avoid personal injury or machine damage.

Avoid rain, water and vapor infiltrating the machine. If there is, dry it and check the insulation of the cutting machine (including that between the connections and that between the connection and the enclosure) with an ohmmeter. Only when there are no abnormal phenomena anymore, can the machine be used.

Put the machine into the original packing in dry location if it is not to be used for a long time.

Generally, periodic check should be carried out every 6 months, and it should be carried out every 3 months if the cutting environment is dusty or with heavy oily smoke.

5. TROUBLESHOOTING

The abnormity indicator on the front panel would illuminate in case of any failures inside the cutting machine.

Malfunction Phenomena

Turn on the machine, the power indicator illuminates, the fan does not work, and the control button does not function.

Turn on the machine, the power indicator illuminates and the fan works. When pressing the control button of the cutting torch, the solenoid valve inside the machine functions, but there is no HF discharge rustling and the red LED inside the machine is on.

Arc can not be ignited.

Cause and Solution

Overvoltage protection occurs: Shut down the machine, and restart it after a few minutes.

1) The MOSFET (or IGBT) on the top PCB is damaged. (The drive module is damaged.)

2) The step-up transformer on the bottom PCB is damaged.

3) The control module is damaged.

The arc ignition part fails:

1) There is electrode sticking inside the discharge nozzle or the interelectrode distance of the discharge nozzle is too long.

2) There is short circuit or bad contact in the primary coil of the arc ignition transformer.

3) There is leakage of the HF capacitor 102/10KV.

4) The relay is damaged.

1) The input voltage is too low.

2) The air pressure is overly high or overly low.
