Brief Description Of Spot Welding Machine Operating Procedures

How much do you know about spot welding machine operating procedures? Today the spot welding machine manufacturers bring you a detailed introduction, let's take a look together.

Preparation before welding

1. Before performing this work, you need to clean the oil on the upper and lower electrodes. Power-on self-test electrical equipment, operating mechanism, cooling and crushing, broken gas path and body shell (with or without leaks).

2. The indoor temperature should not be lower than 15 ° C.

3. Before starting, turn on the control line switch and the small welding current switch, insert the pole position of the pole number adjustment switch, and turn on the water, air and control knobs on the control box. The electrode contacts remain bright.

4. The spot welder controlled by the pneumatic pedal should reflect the pipeline without air leakage and foreign matter blocking.

Second, pay attention to welding matters

1. When welding, cool and remove the gas path and water. The gas should not contain water. The drainage temperature does not exceed 40 ° C, and the flow rate is adjusted according to the rules.

2. The life of bearing hinge and cylinder piston and seal ring should be stable.

3. The task of tightening the upper electrode and adjusting the nut (above the cylinder block) is required. By rotating the handle of the pressure reducing valve, the electrode pressure can be adjusted according to the requirements of welding standards.

4. It is strictly forbidden to add a fuse in the ignition circuit to avoid damaging the tube and the silicon rectifier. When the load is too small and no arc will occur in the ignition tube, it is strictly prohibited to turn off the ignition circuit of the control box.

Three, matters needing attention after welding

1. When the welder stops working, first cut off the power supply, gas source, turn off the water source, and remove debris and splashes.

2. If the welding machine is temporarily stopped, anti-rust oil fingers should be used on the unpainted moving parts. Heat for 30 minutes every month. The thyristor should also be warmed up for 30 minutes, and the normal task control box should be warmed up for not less than 5 minutes.
