The method of attention when spot welding: The selection of current dispatching switch level can be made according to the thickness of welded parts and raw materials. After power is turned on, the power indicator should be on and the spring pressure nut can adjust the electrode pressure size to change its tightness. After the above adjustments are finished, the cooling water can be turned on first, and then the power supply can be turned on for welding.
Welding process procedure: Place the welded part between the two electrodes, depress the pedal, touch and press the upper electrode and the welded part. When the pedal continues to be pressed, the power contact switch opens, so the transformer starts to work and the secondary circuit is energized to heat the welded part. When the pedal is released after a period of welding, the electrode rises, blocking the power supply by spring tension, and then returns to its original state, ending the single-point welding process. During installation, the interval between the welded part of the machine body and the ground should be adjusted accurately according to the production characteristics. As the spot welder works, the welder is often sent to pick up the welded parts and weld them properly. Connection direction can improve the productivity of the welder. For safe operation of the equipment, a safety cut-off switch or a power circuit breaker of appropriate capacity should be installed near the welder. If the equipment is to be adjusted or repaired, the power should be cut off first, otherwise it can cause serious accidents.
Spot welding machine manufacturers remind spot welding machine use details: spot welding machine manufacturers remind you spot welding stainless steel is easy to generate heat and heat dissipation, spot welding machine spot welding rate is an important welding function of the welded material, high resistivity, poor electrical conductivity (such as stainless steel), but also to a certain extent inhibit the growth of the interface reaction layer. Due to the thermal conductivity of aluminum alloy compared to spot welding, a T-spacer made of steel is clamped between the aluminum alloy plate and the electrode to improve the thermal analysis of the aluminum side. This spot welder was used for welding equilibrium and nucleus deflection, and the T-spacer method was used for resistance spot welding of aluminum-steel heterogeneous materials.
