  • The solutions of welding head problem: do not feed wire
    Jan 14, 2023 The solutions of welding head problem: do not feed wire
    Operating logic:the wire feeder connects to the 5/6 pin of the signal interface of the control box by the two-core plug signal lines in the terminal. When the system is running, the built-in relay in the control box mainboard and 5/6 turns on, and the wire feeder starts to work (that is, the 5/6 pin controls the on-off). When there is an outflow of light but no wire: First look at the setting of the wire feeder, whether the pulse parameters are normal. Please set according to the figure (individual versions do not have a pulse function, you don’t need to set) If all the above is no problem, we first determine whether there is a problem with the control of the wire feeder Click on the front panel of the wire feeder [Manual Wire Feeding] to observe whether the wire feed wheel is running 1. If the wire feeder does not run, the wire feeder itself has a problem, and please replace the mainboard. 2. If the wire feeder runs, please continue to operate according to the instructions below. We first short the signal line of the wire conveyor, which located in the tail of the wire feeder with two cores of the plug, and after unplugging, to find a wire to short connect 1. If the wire feeder is running, you can determine that the wire feeder is no problem, and please continue to follow the following operation. 2. If the wire feeder is not running, it can be determined that there is a problem with the wire feeder mainboard and please replace the wire feeder mainboard. In the first case, plug in the two-core aviation plug at the tail of the wire feeder, and unplug the 5/6 pin of the signal interface of the system control box. Then shorten the signal line of the wire feeder (not shorted to 5/6 pins). 1. If the wire feeder is not running, it can be determined that there is a problem with the signal line, and to replace the signal line is Ok. 2. When the wire feeder is running, it can be determined that there is a problem with the system mainboard, and please replace the system mainboard or use the following measures for a temporary use. The signal line of the wire feeder is controlled by the 3/4 pin of the signal interface two to control the signal line on and off, and the wiring is defined as follows (the two-core signal of the wire feeder uses the normally open foot of the relay)

  • The solutions of welding head problem: the electric machinery does not swing
    Jan 14, 2023 The solutions of welding head problem: the electric machinery does not swing
    The normal spot becomes a spot line (left) by swinging the electric machinery, and if the motor is not swinging, then a dot will be displayed (right). The analysis of causes: One. Whether the software section is set correctly Settings - Scan Correction: 1.25 Process - Scan width: welding system 3-5 and cleaning system 20-150 Home - Indicates Red Light turns on Two. Check hardware section 1. The power supply of the swing motor is 15V power, we should first measure whether the power supply of the 15V switching power is normal. 2. In addition, the 15V switching power supply is divided into positive and negative, the wrong wiring will also cause the motor not to work. V1 is connected to 15V+, V2 is connected to 15V-, and any COM on the 15V switching power supply is connected to the No. 2 pin GND! 3. (Model SUP20S/T/C) Check whether the interfaces at both ends are inserted in place and whether there are any mistakes on the drive board 4. (Model SUP15S) If the power supply is normal, it is generally caused by a broken circuit. The control box and the motor are powered by a 2-core wire, focusing on checking the 2-core wire of the air plug, and disassembling to see if the circuit is broken 5. (Model SUP15S)When there is no problem with the 2-core wire, check the signal insertion of the 5-core wire, and also disassemble it to see if there is a broken circuit 6. Check whether the rainbow link between the mainboard and the driver is loose or not. 7. When all the above cannot be handled, please replace a motor cable. As to the skill, we can communicate in group.

  • The solutions of welding head problem: electric machinery swing abnormally
    Jan 12, 2023 The solutions of welding head problem: electric machinery swing abnormally
    Problem symptoms: After power-on, the welding head’s tail electric machinery appears to whistle / the red light of swing appears to be abnormal / heat / unable to adjust the swing width. Causes and solutions to the problem: The driver controls the swings of electric machinery in the control box. And the above problems may occur when there is a signal error or the drive does not match the electric machinery. We should check whether the wiring is normal at first, and then deal with the abnormal sound by adjusting the drive of electric machinery, the specifics are as follows: ① Poor connection between the connecting wire terminals of the electric machinery and the driver (SUP20S model) In the SUP20S welding gun, we take the way of the connection terminal to be built-in. However, poor connection may cause the signal to be abnormal and cause a whistle. If in this situation you should try to unplug and plug again. ②The connection line between the driver and the electric machinery is in a broken circuit (SUP15S model) On the SUP15S welding gun, the electric machinery signal and power supply are connected through the air plug interface (two black lines), and the air plug interface should be disassembled to check whether the soldering pins are broken or virtually welded. ③Premise: If the swing is normal, there will be no redlight flickering, and the wiring is confirmed to be no problem. It means that the driver and the electric machinery do not match or be interfered. This appears on newly installed equipment or equipment whose tip be replaced, and it can be improved by adjusting the driven potentiometer. Potentiometer position: Y axis (on the left side of the figure below) above the   plug from left to right, the seventh position is the potentiometer. The method of adjustments: in the powered state, please use a slotted screwdriver to twist in one direction. If there is no response for more than 10 turns, please reset after twisting back, and then continue to twist in another opposite direction. (If the adjustment of the seventh potentiometer does not respond, then to adjust the one that counting from left to right is the fourth one).

  • Welding head problem: burning copper nozzle
    Jan 12, 2023 Welding head problem: burning copper nozzle
    The analysis of causes: During the welding process, there is heat diffusion to the copper nozzle which may damage it. In the treatment process, we should analyze the heat source at first, to check which one to transfer heat. The lens astigmatism, red light bias or external material. Solution: This should be ensured before processing ①The red light is centered (the polarized light will cause the light to hit the mouth). ②Suitable scanning width (generally it is within 5, and usually we will set to 3) ③Focus 0 focal length (scale tube is 0 is enough) 1. First of all, the light is far away from the ground, and look at the copper mouth to check if it is hot. If it is not hot, which means that the lens has no problem and there is no astigmatism. If it is hot, and the damaged lens needs to be replaced. 2. In the above normal cases, if the welding is hot, it means that the material transfers heat when in the welding process. So in the actual use process, the outer corner copper nozzle is more easily damaged than the inner corner, and the copper nozzle can be used to solve this problem. 3. Welding techniques also affect the hot. Welding head and material should be at 45° welding as much as possible. 4. Highly reflective materials such as aluminum plates can also cause copper nozzles to be hot, which is uncontrollable.
