AC spot welder with welding, brazing, projection welding, etc., the principle of welding is to convert the industrial frequency alternating current into low voltage, large electric flow through the resistance welding transformer, in the electrode to the workpiece under a certain working pressure for welder. Effective control of welding quality, welding link spatter volume reduction, improve welding quality, the use of integrated welding, strengthen the welding function, bring welding quality inspection data and monitoring integrated modular design, welding automatic control system stability. By the digital integrated manipulation or microcomputer controller to manipulate the conduction angle of the SCR and the length of opening, completed the size of the welding current and the length of opening, electrode pressure on the workpiece by the pneumatic system.
Adopting three-phase balanced load and medium frequency welding technology, no need to add capacitive compensation cabinet. Digital medium frequency welding, energy saving more than 30%, greatly reduce energy cost. Precise control of welding parameters (1MS) enables efficient welding of, multi-layer steel plates/variable thickness ratio steel plates/high tensile steel plates/aluminum alloys. The welding transformer is small in size and weight, in line with the application of industrial robots and integrated welding tongs. HMI operation, user-friendly operating software, saves time and effort.
Daily maintenance: to ensure long-term normal operation of the equipment, you should ensure that the equipment is clean inside and outside, not too wet, regular maintenance of part of the circuit for shaking, insulation is good.
The mechanical part should be filled with lubricant regularly, the clearance of the active position should be checked, the matching between the electrode and the electrode grip should be checked whether it is normal, the air and water pipelines should be blocked, and there should be no shaking of the electrical contact. If part of the electrical control of the equipment is faulty, maintenance should be carried out as soon as possible.
