eBay DC 12V Portable Transistor Mini Spot Welding Welder Machine LCD Display DIY WM-1 Reference description: Note, read before use: Battery selection: 1. 12V car battery from 25 to 40ah, requires good performance and low internal resistance 2. 4000 to 6000 mAh 45C to 60C 3S aircraft lithium battery 3. 30 to 35ah 12V capacity lithium battery pack Selection of welding materials: 0.1-0.12mm thick nickel-plated steel strip Energy setting The energy must gradually increase from 01, and the maximum cannot exceed 50. It is recommended that the energy be below 30 Exceeding the above conditions may damage the controller! Instructions for use: 1. Power wiring The controller comes with a 20cm long 10AWG input wire, one end has been crimped with the U-shaped terminal, and the other end has not been processed. Connect the crimped U-shaped terminal to the input end of the control power supply, and handle the other end according to your own power supply. Note, do not connect the positive and negative poles wrong 2. Switch machine There is a power switch under the control panel. After pressing it, wait for 3 seconds. After the buzzer beeps, the LCD lights up and the boot is completed. Press the power switch again to shut down. 3. Screen description and parameter adjustment There are currently three parameters on the screen WELD ENERGY: Welding energy, parameters 01-99 INPUTE: Power supply voltage displays the current input power supply voltage WELD WAY: Welding method, MANUAL manual and AUTO automatic Welding energy adjustment: can be adjusted directly by pressing the up and down buttons Welding method selection: can be switched by the third button 4. Welding Press the welding pen obliquely onto the nickel strip to keep the welding needle clean. According to the actual test, if the welding needle is ground into a round head, the welding effect can be improved There are two ways of welding: manual and automatic. In manual mode, you can make a trigger switch by yourself. The plug of the controller can be plugged into the manual trigger socket of the controller. Each time you press the trigger switch, the buzzer will sound twice to complete one welding. In the automatic mode, when the two welding pins touch the nickel strip, there is a delay of 1 second, the buzzer emits three beeps, and one welding is automatically completed. Common problem: If the spot welder of this version cannot be welded or welded firmly! Generally, it is the following situations: 1. The battery or the power supply current is too small: the principle of spot welding is that the short-circuit power supply produces high-temperature molten metal materials for welding. If the power supply current is too small, the welding will not be possible, or the effect will not be good! 2. The wiring is not connected properly. Because there is a large current. The wiring must be screwed to the power supply. And the contact area should be as large as possible, if you use a clamp to clamp the battery, or use a wire to screw on the electrode It is absolutely impossible to have a good effect! 3. Improper gear setting. The board is equipped with 50 gears. Generally, it is recommended to reach 30. For a small discharge current, use a higher gear. If it is adjusted to 30 and the point is not strong, it proves that the battery current is too small and only Replace the battery with better performance! Or check the connection. Is it connected? 4. For operation: you need to press 2 soldering pens together on the nickel sheet, press and hold, there will be a current output in about a second, and you can take it off immediately if you can’t click it! Note, just tap it, welding The pen and the nickel sheet are at a 45-degree angle. 5. Be sure to choose the right battery, the energy adjustment needs to be increased step by step, otherwise it will be very easy to blow up the MOSS tube 6. Note that only nickel sheet steel strips can be welded Specifications: Material: Metal Input line length: app.20cm/7.87in Length of welding pen: app.30cm/11.81in Color: Red+Blue+Black Battery: lithium battery(not included) Quantity: 1Set Package Included: 1x Controller 1x Welding pen 1x Power input line (Red and Blue) 1 Pair x U-shaped cold-pressed terminal (used to connect to input power) Several heat-shrinkable tubes, used to shrink the power input line Notes: Please allow 1-3 cm difference due to manual measurement. Due to light and screen difference, the item’s color may be slightly different from the pictures. WM-2 Reference description: Features: Brand new LCD display interface, more intuitive and clearer data display Brand new MOSFET drive design, providing greater drive current and switching speed Re-layout of components, more reasonable PCB design Adopt 4MOSFET design to minimize the problem of MOSFET mismatch Power supply selection 1: 12V car battery from 25 to 40ah, requires good performance and small internal resistance 2: 4000 to 6000mAh 45C to 60C 3S model airplane lithium battery 3:30 to 35ah 12V capacity lithium battery pack Note: Can not use super capacitor as power supply Welding nickel strip selection The thickness of the welded nickel strip should be 0.1 to 0.12mm Exceeding this thickness may cause the MOS tube to burn out Energy setting The energy must gradually increase from 01, and the maximum cannot exceed 30. It is recommended that the energy be below 30. Exceeding the above conditions may damage the controller! Switch machine In the shutdown state, long press the square button, the buzzer will beep three times, and the controller will turn on In the power-on state, long press the square button, the buzzer will beep twice, and the controller will shut down parameter settings There is only one parameter that needs to be set to control the welding energy. The larger the parameter setting, the higher the welding energy. In the power-on state, use the up and down triangle buttons to set the welding energy parameters Mode selection There are three working modes for control STOP MANUL AUTO STOP: In this state, the controller cannot be welded MANUL: manual welding mode, welding through an external trigger switch AUTO: automatic welding, when the soldering pen touches the nickel strip, the delay is 1 second, and the welding is automatically completed Welding operation Select the automatic mode, set the energy to 1 first, and then put the nickel belt on the test machine (don’t weld the battery yet) If the welding is not possible, gradually increase the energy until it can be welded, do not increase the energy Before completing the welding, make sure that the soldering pen is firmly crimped onto the nickel strip, otherwise it will blow through. common problem: 1: Cannot be welded the reason: Generally, the battery capacity is too small and the ability to release current is insufficient Nickel belt is too thick Solution: Choose a battery that meets the requirements Welding nickel tape between 0.1mm and 0.12mm 2: Welding explosion fire, nickel belt perforation the reason: Too much energy The soldering pen is not firmly pressed There are flammable materials under the nickel belt Solution: Energy down During the welding process, keep the welding needle completely firmly crimped on the nickel strip During the welding process, no flammable materials must be placed under the nickel belt 3. MOS tube burned out during welding the reason: Battery capacity is too large Nickel belt is too thick Solution: Choose a battery that meets the requirements Welding nickel tape between 0.1mm and 0.12mm Package Included: 1X Controller 2X Soldering pen 2X Power cord 1X Manual Shipping Feedback Contact us Return Policy Shipping Domestic We believe you need to get your purchases as quick as possible.
