Common resistance welding machine problem solving

First, the precision resistance welding machine step foot pedal welding machine does not work, the power indicator is not bright: the power supply voltage is normal; Whether the control system is normal; Foot switch contact, switch contact, split shift switch can fight well or burn out.

Second, the power indicator is on, the workpiece is pressed and not welded: whether the pedal stroke can be in place, whether the foot switch can fight well; Pressure rod spring screws can be properly adjusted.

Third, the precision resistance welding machine welding should not show the splash: whether the electrode head can be oxidized; Whether the welding workpiece can be strained and corroded badly; Adjust the switch whether the gear is too high; Whether the electrode pressure is too small, and whether the welding pace is accurate.

Fourth, spot welding machine solder joint indentation tension and extrusion: whether the current is too large; Whether the welding parts are uneven; Whether the electrode pressure is too large, whether the shape and section of the electrode head are suitable.

5, spot welding machine welding workpiece strength is insufficient: whether the electrode pressure is too small, whether the electrode rod can be fastened; Whether the welding energy is too small, whether the welding workpiece can rust and strain, so that the welding joint is bad; Whether there is too much oxide between the head and the electrode rod, the electrode rod and the electrode arm; Whether the cross section of electrode head will increase due to wear, resulting in a decrease in welding energy; Electrode and copper soft connection and bonding surface can be tense oxidized.

6, spot welding machine when the exchange war sound abnormal: exchange war wire voltage in the welding can be lower than its own release voltage 300 volts; Whether the power lead is too thin and too long, forming the line voltage drop is too large; Whether the network voltage is too low to work properly; Whether there is a short circuit in the main transformer, resulting in too much current.

Seven, precision resistance welding machine overheating phenomenon:

Whether the insulation resistance between the electrode base and the body is poor, forming a local short circuit; Whether the inlet pressure, water flow rate and water supply temperature are suitable, whether the waterway system is blocked by dirt, resulting in overheating of the electrode arm, electrode rod and electrode head due to poor cooling; Whether the copper soft connection and electrode arm, electrode rod and electrode head fighting surface can be oxidized and tense, forming fighting resistance and increasing heating tension; Whether the section of electrode head can increase too much due to wear, so that the welding machine overload and heat; Whether the welding thickness and load continuity rate exceed the standard, so that the welding machine is overloaded and heated.
