If you encounter a mask spot welder failure, don’t rush to see our solution!

In the normal use of mask spot welding machines, there will be some various failures. If they are not handled properly, it will affect the production progress. This is a problem that many manufacturers want to deal with. Then, what are the common problems of disposable mask spot welding machines Trouble? Let's take a look at the introduction.

Mask spot welding machine

　1. No action after starting

　　 1. Reason: insufficient air pressure

  Solution:

　　 (1) Whether the air pressure is above 1kgf/cm2.

　　 (2), the pressure reducing valve is defective.

　　 (3), O-ring seal leaks, replace O-ring seal.

　　 (4) There is no oil in the pressurizing head, please fill in oil.

　　2. Reason: bad solenoid valve

  Solution:

　　 (1), manual operation, solenoid valve coil, wire connector.

　　 (2), manual operation does not work, spool valve lacks oil, spring is defective.

　　 3. Reason: bad start switch

  Solution:

　　 (1), the switch is defective.

　　 (2), the wire is broken.

　　 (3), the connection terminal is poorly connected.

　　 4. Reason: The control part and the welding power supply are not connected

  Solution:

　　 (1) Whether there is power supply voltage in the loop.

　　 (2). Check that the wiring is firmly connected.

2. Black or pits

　　 1. Reason: too much heat

       Solution: reduce the heat value.

　　2. Reason: insufficient air pressure

      Solution: Increase the air pressure.

Third, the indentation is too deep

　　 1. Reason: Welding pressure is too high

       Solution: Reduce the air pressure.

　　2. Reason: excessive welding heat

       Solution: reduce the heat.

　　 3. Reason: The electrode tip area is too small

      Solution: Grind the electrode tip to an appropriate size.

Four, abnormal splash

　　 1. Reason: insufficient welding pressure

       Solution: Increase the air pressure.

　　2. Reason: The electrode tip is not flat

      Solution: Smooth the electrode tip.

Five, no current

　　 1. Reason: welding circuit

　　Solution: The welding circuit is blocked and the workpiece is seriously dirty. Please clean the workpiece.

　　2, reason: no trigger

　　 Solution: Replace the motherboard.

Six, the temperature control switch is off

　　 Reason: The temperature is too high

  Solution:

　　 (1), no cooling water: the water path is blocked or the water flow speed is not enough. Supply enough cooling water to clear the cooling water circuit.

　　 (2), continuous working time is too long: overload use, reduce the load duration (reduce the frequency of use).

Seven, the cylinder is not sensitive or does not move

　　 1. Reason: the regulating valve is screwed or broken

       Solution: Check the regulating valve.

　　2. Reason: the solenoid valve wire package burned

        Solution: Replace.

　　 3. Reason: Cylinder cushion adjustment is too tight

       Solution: adjust appropriately.

　　 4. Reason: insufficient air pressure

       Solution: increase the origin pressure.

　　 5. Reason: the cylinder shaft is stuck

        Solution: adjust
