Welding nickel sheet thickness: 0.1-0.3mm (related to battery discharge energy)
Commonly used power supply: high-rate lithium battery, lead-acid battery, high-rate lithium iron phosphate and other lithium batteries.
Functional tests:
1. The spot welder board can be powered by lithium 2S, 3S or 4S lead-acid batteries, and the supply voltage needs to be
between 6.5V and 16V, not in this range may cause damage to the board device.
2. Connect the lines according to the connection schematic, and after power on, select the appropriate capacity, multiplier and
gear and other parameters, and observe whether the indicator is normal.
3. the welding pressure applied to the nickel sheet must be moderate, and the contact surface of the nickel sheet and the battery is free of oil, bumps the contact surface of the nickel sheet and the battery is free of oil, bulges and oxidation. Practice on the surface of iron and stainless steel until the 0.1mm nickel sheet can not be torn off
When you are familiar with it, you can weld the battery.
4. the battery temperature is too low, may cause the battery performance degradation, preheat a dozen solder joints
After a dozen or so preheated solder joints, the pexk performance can be restored, it is best to use in a warm room, timely replenishment of power, low power off after charging, you can wake up again and turn on the battery.
Warm tips:
①Welding is a technique that requires practice, the scientific principle of spot welding is resistance welding, pressure too
Tight or too loose will lead to unsound joints, a successful welding is not a large number of sparks and visible bright dents.
A successful weld will not produce a large number of sparks and visible bright depression welding joints.
The best technique is to lightly press the soldering pencil and feel the collapse of the solder joint at the moment of current output. This
When the heat of the joint is enough, the cooling time is short, and it can work firmly for a long time.
③ Too tight and too loose will lead to poor welding, or burn through phenomenon, and must avoid repeated welding to the oxide layer, should be
Avoid repeated welding to the oxide layer, should ensure that the contact surface is bright.
④With 1-6 grades of different welding intensity to get the best welding joints.
Recommended parameters for use.
– System voltage: 6.5V-16V (best 11.5V-14.8V)
– Working current:100A-900A
Recommended battery:
1, 12V-30-65ah lead-acid battery with good performance, small internal resistance (internal resistance less than 10 milliohms, discharge
(internal resistance less than 10 milliohms, discharge current greater than 100A), such as car starter battery!
2, 4000mah-10000mah, 30-70C, 2S, 3S, 4S model aircraft lithium batteries(4S battery needs to be less than 16V)
3, 30-35ah capacity type 18650 battery pack
4, battery discharge current <900A short-circuit current <1800A, more than this range may damage the control Board!
Operating instructions:
1. Connect the positive and negative battery poles according to the product connection diagram.
2. The soldering pen and the battery connection wire should be locked with the fixing screw, so as not to lead to fire, welding
Not secure, not solid.
3. Press and hold the on/off button for 2 seconds to turn on the power, at this time the power-on indicator will be constantly on (blue light).
4. According to their own battery parameters to select the corresponding capacity (green light), multiplier (blue light), the indicator
light will also be lit accordingly.
5. then short press the gear selection (yellow light) button, you can select the appropriate gear for welding.
6. Find the nickel tab, place it on the positive/negative pole of the battery to be soldered, with the two tips of the soldering pen as close as possible, and gently touch the nickel tab. As close as possible, gently touch the nickel piece, 0 . After 0.5 seconds of automatic output instantaneous pulse welding nickel after each output, the buzzer will sound once, and then you need to move away from the spot welding pen, otherwise it will not be able to the buzzer will sound after each output, and then you need to remove the spot welding pen, otherwise the second output cannot be performed (the purpose is to prevent the welding time is too long and damage the battery).
7. Small capacity 18650 battery and DC power supply can not be used as a power source. It must have a high rate of lithium battery pack or car starter lead-acid battery discharge capacity > 100A!
Button, indicator description:
1. On and off button; long press the on/off button 2S, the device can be turned on and off, while the on/off
The indicator light also lights up or goes off accordingly.
2. Capacity, multiplier, users can choose the corresponding parameters according to their own battery parameters, and the corresponding indicator will light up accordingly.
The capacity indicator is green and the multiplier indicator is blue.
3. Gear button: the function of this button is to adjust the output power of welding, divided into one to six
The power is divided into one to six gears, one gear is the smallest and six gears are the largest, and the gear indicator is yellow.
4. buzzer: buzzer will sound when the machine is switched on and off, in the key selection switch at the same time
The buzzer will sound once when the machine is switched on and off, and will also sound once during each normal welding output.
