How to inspect and debug intermediate frequency spot welding machines?

After the installation of the intermediate frequency spot welding machine, it is necessary to first verify the accuracy of the installation, that is, according to the requirements of the user manual, check whether the wiring is appropriate, measure whether the working voltage of the power supply meets the requirements, measure whether the grounding resistance to ground at each position meets the regulations, whether the grounding device is reliable, and whether the water and gas pipelines are unobstructed.

Once the installation is confirmed to be accurate and error free, it can be powered on for inspection. Power on inspection not only checks the installation quality, but also verifies whether the matching working voltage value of the welding transformer matches the factory nameplate value when the welding transformer is changed in equal proportion based on measurement. It also checks whether the electrical main parameters of each position of the control board and each output signal comply with the regulations in the user manual,

Avoid common faults caused by the operation of intermediate frequency spot welding machines. After inspection and measurement, a full load test run can be carried out. Connect an adjustable resistor with a high resistance value in series between the insulation layer in the middle of the electrode or in the middle of the electrical stage.

Start the welding machine and verify the program flow and charging method of the intermediate frequency spot welding machine. Based on the comprehensive verification above, it is possible to determine the credibility of the control board adjustment, whether the electrode reduction is gentle and without impact, and whether everything is normal during the operation of the charging system software, as well as the coordination ability of each theme activity position posture of the intermediate frequency spot welding machine.
