& ⒈DC output. The welding current is pulsating DC (with small ripples), without the shortcomings of AC zero-crossing discontinuous heating of the workpiece. The heat is concentrated, which improves the welding thermal efficiency. It is especially suitable for the welding of non-ferrous metal materials and some difficult-to-weld materials. The welding process is stable and the welding process is stable. Quality improved significantly. At the same time, the electrode life is extended.
< < 2. Fast response speed. Due to the use of a higher inverter frequency, the power-on time control period is ./, which is the best for industrial frequency welding machines, and the control accuracy is significantly improved. Compared with capacitor energy storage welding machines, there is no need for charging and discharging, and the controllability is significantly enhanced. It is especially suitable for welding precision parts and high-quality, high-precision, and high-speed welding.
< < ⒊Using microcomputer control to ensure the consistency of the process. Multiple sets of welding process parameter storage, parameter adjustment and welding cycle panel intuitive instructions simplify operation.
< < ⒋Three-phase load balance (three-phase input model), and the output waveform is stable. The power of the power frequency AC resistance spot welding machine is relatively large. When connected to the power grid, the three-phase load will be unbalanced and affect the power supply grid. The use of inverter technology reduces power requirements. Single-phase inverter DC is significantly improved compared to power frequency AC, while three-phase input inverter power supply completely eliminates this effect.
< < ⒌Energy saving. Experiments have shown that compared with conventional spot welding, the inverter power supply only needs % energy to obtain welding spots of the same size.
< < ⒍Small size and light weight. Due to the medium-frequency operating frequency, the volume and weight of the welding transformer are significantly reduced at the same power output. It is reported that the weight of the inverter-type integrated welding clamp can be reduced by 10%.
< < ⒎Easy to cooperate with various types of special machines, suitable for automation applications. Strong external communication functions: multi-channel start, welding end, fault, counting signal, R data communication port (optional for some models), convenient for automatic welding.
