The problem of plasma cutting

5.1 no high frequency guidance arc

Check high frequency arc ignition circuit, first check the 110VAC, and observe the G1, G2 whether there is discharge sparks exist. If not, generally 110VAC did not come or fixed G1, G2 plastic board damp, damp after G2, G1 can not discharge and produce high pressure. Drying wood glue with a hair dryer to restore 110VAC. If there is still no guide arc, should check the high frequency arc, due to the high frequency of the skin effect, the high frequency line and the nozzle of the conductive ring is not good or because of the reasons for the sealing ring and the cooling water will not have a short circuit. Open the cutting gun, tighten the high frequency line or replace the sealing ring, generally can solve the problem.

5.2 there is no cutting arc

In the case of a high frequency spark observed, first check whether there is an open circuit voltage 400VDC. If not, check whether the phase of the three-phase power supply. High power silicon controlled rectifier and trigger circuit board in power supply box. If the power supply is normal, open the PLC control box, check the PLC input and output signals. The input consists of cooling water, cutting water flow signal, nitrogen and oxygen pressure signal. Cutting water flow signal without cooling water, cooling water pump should be replaced, without cutting the pump; nitrogen, oxygen pressure signal should be tested for nitrogen, oxygen source, and check whether the pipeline leaks. Such as the start conditions are met, will have to check the cutting gun, electrode rod sealing ring or the nozzle seal damage will water seeping into the cavity between the electrode and nozzle, leading to short-circuit DC power supply and the nozzle, can not form a loop with the workpiece. Replace the sealing ring, re assembled torch that can solve the problem.

5.3 The poor quality of cutting

Is cut not to wear the workpiece, or hang slag, slotted uneven. This is main arc has not been sufficient compression, arc column thicker, the penetration problems caused by, main reason is cutting gas pressure is insufficient or cutting gas pipeline leakage. Combined electromagnetic valve control cutting gas, combination switch and trachea, if the use of imitation of the parameters of the nozzle, wrong, cause the turbulence between the nozzle electrode will also be the case.

5.4 spark generator can't be broken arc

Plasma cutting machine work, first of all to ignite the plasma arc, by the high frequency oscillator excited gas between the electrode and the inner wall of the nozzle, resulting in high-frequency discharge, the gas ionization and the formation of local small arc, the small arc by compressed air and ejected from the nozzle to ignite the plasma arc, which is main task spark generator. Under normal circumstances, the spark generator working time is only 0. 5 ~ 1s, the reason does not automatically break arc is generally offset control circuit board components, discharge electrode gap of the spark generator is not right. Should always check the spark generator discharge electrode, make the surface smooth, timely adjustment of the discharge electrode gap spark generator (0. From 8 to 1. 2mm), it is necessary to change control board.

5.5 poor contact with the ground

The ground is the essential preparation before cutting work a. Without the use of special grounding tool, workpiece surface insulation and long-term aging serious ground, will cause poor contact with the ground. Should use special grounding tool, and check whether the insulation effect of the ground contact with the workpiece surface, avoid the aging ground

We are a professional manufacturer of plasma cutter consumables, Our company is located in the Shanghai City, China ,it was established in 2007,but we had 10 years manufacturing experience in this field, the new factory covers an area of more than 10000 square meters .There are 50-100 workers and 20 research engineers.
