How to adjust the current of the rotor automatic line spot welding machine
In the past, the rotor automatic line spot welder relied on the AC controller and the AC spot welder, resulting in unstable current and common welding defects. Therefore, they are gradually replaced by intermediate frequency inverter DC controllers and intermediate frequency inverters combined with new spot welding machines. Despite this overhaul, this veteran product still requires a precise method for adjusting the current of the rotor automatic wire spot welder. Here are some tips:
1. Using constant power mode control: adopting constant power mode Q=UI can prevent the resistivity and temperature of the electrode from becoming high when using constant current mode control. In this way, the occurrence of the rising phenomenon of thermal energy Q=I2Rt is avoided, and the thermal energy is balanced.
2. Place the two rotor car wires used to measure the voltage as close to the positive and negative poles as possible. The main focus is on controlling the voltage between the positive and negative poles, not the voltage across the entire circuit.
3. Change from single-pulse discharge to two-pulse or three-pulse discharge (keep the total discharge time unchanged), and reduce the power value to the minimum (that is, the current is as small as possible). With pulse discharge, the power value needs to be increased to achieve the required welding heat. But using double-pulse discharge (when setting parameters, set the first pulse discharge value to low and the second pulse discharge value to high) can significantly reduce the set power value (current), while achieving the same level of required Thermal vitality. By reducing the power value (current), electrode wear is minimized and welding stability is significantly improved. According to Q=I2Rt, higher current will cause more heat accumulation. Therefore, while setting the parameters, minimize the current value (power value).
4. Replace the tungsten electrode of the hook under the spot welding machine, so it is the negative electrode. This modification reduces the flow of metal atoms to the tungsten electrode due to "electron migration" when current flows from the hook to the tungsten electrode, which would otherwise stain and deplete the electrode. The term "electron migration" refers to the movement of metal atoms due to the flow of electrons. It is often called metal migration because it involves the flow of metal atoms.
These are some practical tips on how to adjust the current of the rotor automatic wire spot welding machine to improve the working results. Additionally, to maintain accuracy, routine maintenance should be incorporated into the operation of the automated rotor line.
