Use method of spot welding machine:
1。 When welding, the orientation of the electrode pole should be adjusted first so that when the electrode is pressed to the weldment, the arm of the electrode should be kept parallel to each other。
2。 The series of current dispatching switch can be selected according to the thickness of welding parts and raw materials。 The power indicator lamp should be turned on after electrification。 The pressure of the electrode can be adjusted by adjusting the tension spring pressure nut, and the degree of tightening can be changed。
3. After the above-mentioned adjustment, the cooling water can be connected first and then the power supply can be connected to prepare welding. The procedure of welding process: the welding piece is placed between two electrodes, the foot pedal is pressed, and the upper electrode is contacted with the welding piece and pressurized. When the foot pedal is pressed down, the power contact switch is connected, so the secondary circuit of transformer start operation is electrified to heat the welding piece. When the pedal is loosened after the relative time of welding, the electrode rises, the power supply is blocked by the tension of the tension spring and then restored to its original state, and the single spot welding process is completed.
4. Welding parts preparation and equipment: Before welding, dirt, oil stain, oxide scale and rust must be removed. For hot rolled steel, it is better to remove oxide scale by pickling, sandblasting or grinding wheel. Although the uncluttered weldments can be spot welded, the service life of the electrodes is seriously lowered, together with the production power and quality of spot welding. The medium and low carbon steel with thin coating can be welded directly.
In addition, users can refer to the following process data when using:
1. Welding time: When welding medium and low carbon steel, this welding machine can use strong specification welding method (instantaneous power-on) or weak specification welding method (long-time power-on). Strong standard welding method should be adopted in many production processes. It can trudge output power, reduce power consumption and reduce workpiece deformation.
2。 Welding current: Welding current depends on the size, thickness and contact appearance of the welded parts。 Generally, the higher the conductivity of metals, the greater the electrode pressure, and the shorter the welding time。 The current density needed at this moment also increases。
3。 Electrode Pressure: The purpose of applying pressure to the weld is to reduce the contact resistance at the weld and ensure the required pressure when the weld is formed。
