DIY Spot Welder Handheld Portable Mini Spot Welding Machine With Quick Release Pen Nickel Plate 18650 Battery Spot Welder

Spot Welding Machine Manual
1.Functional Test (In cold areas need to be warmed up indoors)

Power on: Long press and hold the panel button for 3 seconds, then power on after hearing "BIBI" twice

Welding gear switching: Short press the panel button to switch from the first gear to the fifth gear.
Shut down: Long press and hold the panel button for 3 seconds, then shut down after hearing a long beep of "BI..."
Automatic shutdown function: Automatic shutdown after 30 minutes of no work.
2. Welding Test
Connect the two soldering pens to the sockets of the main unit respectively.Put the battery to be assembled firmly,

put the nickel sheet on the battery to be welded with left hand, and hold the two soldering pens with right hand,

the pen tips of the two soldering pens are about 3mm. Then, lightly press the welding pen tip to the place where
the nickel sheet and the battery need to be welded. After 1 second, the host will automatically output current for welding.

A muffled noise should be heard at this time . After removing the welding pen, you can see two welding points.
3. Advanced Skills
Welding is a technique that requires practice. The scientific principle of spot
welding is resistance welding. Too tight or too loose pressure will cause the solder
joints to be weak. A successful welding will not produce a lot of sparks, and the
visible light is concave. The best technique is to lightly press the soldering pen to
feel the collapse of the solder joint at the moment of current output. At this time,
the solder joints are hot enough and the cooling time is short, which can work firmly
for a long time. Too tight or too loose will lead to weak welding. Or burn through
phenomenon occurs, and the oxide layer of multiple soldering must be avoided, and the
contact surface should be bright. Cooperate with 1-5 gears of different welding
strengths to obtain the best solder joints.
4. Maintenance
The spot welder should avoid bumps and dampness as much as possible. Make sure that
the welder is turned off when stored. The power consumption is very small, it can stand
by for more than two years.
Ordinary use, need to be fully charged, TYPE-C charging regardless of positive and
negative, guarantee 5V/2A, the battery indicator flashes during charging, after the four
grids are full, welding can be carried out at this time, please pay attention to the
temperature of the welding machine housing for a long time. The shutdown is protected
above 60 degrees.
In order to extend the energy of battery as much as possible, please store it after
fully charged to ensure sufficient power. (Long-term storage)
5. Simple Troubleshooting
A. Familiar with the content of
advanced skills in section 3, strong welding requires an understanding and practice of
the principle of electric welding.
B. Maybe the power supply is out of power, charge it. C. Check if the USB charging port is damaged by unplugging and plugging
vigorously, and the cable is burned. When unplugging and plugging, it must be straight
unplugged and plugged in. Do not move back and forth.
D. Check whether the battery is dead, the
voltage measured by the multimeter with the two soldering pens open is the battery
voltage.
The above faults may be encountered by novice players and can be easily checked.
