Ready to work: 1 Oil filling: Close the oil outlet valve and the intake valve on the oil storage tank. Put the car gasoline (can be 90-98) into the tank through the fuel filler, and then tighten the oil cap. Do not overfill when refueling, leave some space, and pay attention to safety. Ignition use: 1 Open the torch and preheat the oxygen regulator valve to give a small amount of oxygen. Maintenance of plasma torch 1. Assemble the torch correctly. (1) torch collision; Precautions: (1) Do not apply grease to the torch;
2 Install the cutting tip: Select the appropriate torch and cutting nozzle according to the thickness of the cut steel plate. When installing the cutting nozzle, wipe the angle with the angled cone and tighten the nut.
3 Connect oxygen: Connect the oxygen cylinder to the oxygen pipe joint on the torch with a special oxygen pipe, and open the total valve on the oxygen cylinder to adjust the pressure reducer.
4 Check torch firing performance: Turn off the cutting oxygen valve of the torch. Open the preheating oxygen valve and the gasoline regulating valve to touch the thumb to the inlet of the gasoline inlet joint. If there is a suction in the mouth, the torch has normal suction performance and can be used. If there is no suction or even gas overflowing from the gasoline inlet joint, it indicates that the torch has safety hazards and must be repaired and eliminated before use.
5 Connect the oil pipe: connect the oil outlet on the oil storage tank and the gasoline hose joint on the torch with a special oil-resistant and pressure-resistant hose, and fasten it with a special pipe clamp (if the oil outlet of the oil storage tank has a screw buckle) Tighten the nuts at both ends of the tubing. Note that the oil outlet end of the reservoir and the torch end of the torch are left-threaded.)
6 Open the oil valve: Unscrew the oil outlet valve on the oil storage tank. This valve should be open during operation.
7 Open the intake valve: Open the inlet valve of the tank to connect the tank to the atmosphere.
2 (Method A:) Place the open flame on the cutting tip and slowly unscrew the petrol valve to supply oil to the ignition; then adjust the preheating flame as needed. (Method B:) Slowly unscrew the gasoline regulating valve, see the gasoline sprayed in a mist, and adjust the oil mist flow to an appropriate amount, then ignite with an open flame. Then adjust the preheating flame as needed.
3 Preheating and cutting: Same as acetylene torch.
4 When the flame is turned off, the gasoline valve should be closed first, then the preheated oxygen valve should be closed.
5 After the work is completed, be sure to close the oil outlet valve and intake valve and the oxygen cylinder valve in time.
6 In use, if the torch enters the storage tank due to malfunction or improper operation of the torch, it must be stopped immediately. The oxygen retained in the oil storage tank and the gasoline pipeline system should be completely removed before use.
2. The consumables should be replaced in time before they are completely damaged.
3. Clean the connecting threads of the torch.
4. Clean the contact surfaces of the electrodes and nozzles.
5. Check the gas and cooling gas daily.
6. Avoid damage to the torch collision.
7. The most common causes of torch damage:
(2) Destructive plasma arc due to damage to consumable parts;
(3) Destructive plasma arc caused by dirt;
(4) Destructive plasma arc caused by loose parts.
(2) Do not overuse the lubricant of the O-ring;
(3) Do not spray splash-proof chemicals while the protective shell is still on the torch;
(4) Do not use the manual torch as a hoe.
