Hand-held Spot Welder
Welding Machine for Laptop Mobile phone Battery 220V
Hand-held precision spot welder’s working principle is double-sided
double-point cross-flow soldering method. When it is working, two electrodes
exert pressure that makes the metal produce contact resistance. While the
current flowing from one electrode to another, a heat fusion was formed between
the two electrodes. Also a current loop was formed at the same time. These will
not hurt internal structure of work piece.
• Welding traces are clear, small spark, without any
phenomenon of depression and flow of liquid. The phenomenon of low pressure and
water has been perfectly solved. It is an ideal equipment for your production
and assembly cells
control circuit is using SCR discharge pulse circuits and digital program to
control circuit. It can be directly
and accurately adjust the parameters
of solder pin and distance between two pins can be adjusted independently
• It can be
• Can weld: laptop battery, mobile phone battery, button battery,
rechargeable battery, battery pack and 18650 battery etc.
power supply: AC 220V
mode: Double pulse

starting, chek if the two solder pins have been put together (A short
circuit will cause the fuse blown)
can be adjustable from 0 to 99A.
Adjust it to 20—25A is
suitable, when comes to laptop battery, button battery, battery pack or 18650
adjust the current to 30A,
the fuse may be blown if continuous welding. It is because of the working
principle and this will not do harm to the machine. The output voltage is only
3V, it is very safe.
