Great for spot welder machine replacement parts.
Lightweight and small size, portable.
Users need to bring their own 12V battery for power supply, the welding current is about 90A~150A, and it is easy to weld the common 0.1mm~0.15mm nickel plated sheet.
System voltage: 12V-14.6V (below 12V will stop)Specification:Working current: 90-150A (lower than 90A, welding will not work, higher than 200A, it will damage the board, note that this refers to the short-circuit current, not the battery capacity.)
Battery recommendation:
36-45ah Start-up lead-acid battery with good performance and small internal resistance (you must be able to start a car, but not more than 45AH. If the battery is too large, the board will , if it is too small, it will not work. If it is a motorcycle If the performance of the battery is not good, you can connect 2 batteries in parallel to increase the current) 3.5-5.5ah 3S model airplane lithium battery pack above 45C, high-rate lithium battery pack, etc.
Switch function: press the switch for 1.5 seconds to switch (blue light: low power, green light: medium power, red light: high power)Size Chart:Circuit Board: 64x39mm / 2.52x1.54inch.Package Includes:1 Piece Circuit Board.
1 Piece 0.1x6mm Nickel Sheet(1m)
2 Pieces Wires.
2 Pieces Output Line Includes 2 Pens.
3 Sets Screws.
4 Copper Ears.Note:Color might be slightly different due to the color calibration of each individual monitor.
