1 Set Spot Welder Handheld Spot Welding Pen Copper Hole

1. Built-in MOS tube, which can carry 550A current
2. Integrated design, just connect the battery to use
3. The copper needle can be disassembled and replaced
4. 99 levels of stepless adjustment, more convenient to use
5. With a trigger button, press for welding, very convenient. Built-in LED indicator. Spot welding material: 0.1mm nickel-plated strip. Welding pin specification: 3MM x 1.5MM x 40MM professional aluminum oxide brazing pin. Can the copper needle be replaced: yes

Use points:
1. It is recommended to use a 12V 20AH-60AH lead-acid battery with good performance, or a high-rate 3-series or 4-series power lithium battery pack, or a car emergency start power supply as the power input. (Must have good performance, at least the level that can start the car, Voltage range 12V-16.8V)
2. The interface should be , and the wires should not be extended randomly. The spot welding should start from low power and slowly adjust upwards enough to avoid excessive current affecting the performance of the MOS tube. Do not reverse the electrode at the input end, and do not use it beyond the specified voltage range
3. It is recommended to weld the nickel-plated steel strip within 0.1mm, and the effect of 0.2mm can also be obtained by superimposing 2 of welding. Pure nickel or copper aluminum cannot be welded.
