Tape Cutting Machine-

Third, pay attention to the operation process:
1. The torch is in contact with the workpiece and can be cut by pressing the button. Cutting can be started from the edge of the workpiece. When the thickness of the sheet is not large, it can be cut at any point of the workpiece. The torch can be perpendicular to the workpiece
Or slightly inclined to one side, but when opening in the middle of the workpiece, the torch should be tilted slightly to one side in order to blow off the molten metal and cut through the metal.
2. Press the handle button and keep the main circuit on, while the high frequency oscillator works until the cutting arc is formed, and the high frequency oscillator stops working. Thereafter, the cutting can be performed by the movement of the torch. At the same time, the cutting indicator lights.
3. The cutting must be cut through the metal to move evenly, otherwise the nozzle will be damaged. Moving too fast or too slow will affect the quality of the cut.
4, cutting air pressure adjustment: cutting air pressure is too high, the flow is too large, will affect the cutting thickness. If the cutting air pressure is too small, it will affect the service life of the nozzle.
5. Before lifting the torch away from the workpiece, the handle button must be turned on. At this time, the plasma arc is extinguished and the cutting process is stopped.
6. During the cutting process, the arc is re-arced because the torch leaves the workpiece more than 2 mm and the arc is extinguished.
7. When the main transformer temperature exceeds 110 °C due to the connection working time is too long, the thermal protection switch will operate and the device will automatically shut down and cannot be started. It should be restarted after the transformer has cooled down.
8. Always remove the accumulated water in the filter pressure reducing valve, that is, rotate the lowermost screw counterclockwise to remove the water and then tighten. If there is too much water in the compressed air, consider adding a filter valve between the filter pressure reducing valve and the gas source, otherwise the cutting quality will be affected.
9. When the workpiece is not cut, press the torch button as little as possible to avoid damage to the machine.
10. After the cutting workpiece is finished, cut off the power switch and the air supply valve.

Semi-automatic cutting machine technical operation rules
1. Scope of application
The semi-automatic cutting machine is a device for cutting medium and low carbon steel by flame using oxygen-acetylene (medium and low pressure) as a heat source. The machine can cut the straight line, the circle and the arc and the left and right 45 degree groove.
2. Qualification requirements for operators
2.1 The operator of the machine must be trained in safety professional skills.
2.2 The operator must understand how the machine is used and can handle faults that occur during operation.
3. Mechanical requirements for the working environment
3.1 This machine should not be used and stored in high humidity and high corrosion environment.
3.2 It is not advisable to carry out open-air operations in rainy and snowy weather and windy weather. If necessary, cover measures should be adopted.

4. Mechanical operation
4.1 All parts must be carefully inspected before use and then tested. At the same time, check the gas distribution valves and torches and the connection path. If there is no problem, ignite and observe whether the flame is normal. If there is no problem, it can be cut.
4.2 When cutting straight lines, it is necessary to put a special track on the steel plate to be cut, select the cutting nozzle according to the cutting thickness, and adjust the speed before cutting.
4.3 Pressure automatic switch and pneumatic valve are normally open. When using automatic pressure switch, the knife switch at the label pressure switch should be pointed in the direction of closing. At this time, the pressure automatic switch is turned on during cutting. When walking, if the automatic switch is not used, the knife switch is pointed to the open position, so that the operation and stop of the cutting machine can be controlled only by controlling the on/off of the power label.
4.5 When cutting the circle, the radius rod should be installed in the screw hole of the body shell and locked, then the tip of the fixed needle should be placed in the hole of the pre-cut center, and the fixed needle can be adjusted to lift the cutting wheel of the cutting machine. To cut, if you need to cut the groove, you can reach the torch by turning it through a certain angle.
4.6 The forward and backward movement of the cutting machine (ie, forward and reverse operation) can be controlled by controlling the middle and reverse signs.
