function test:
1. The spot welder board can be powered by lithium battery 2S, 3S or 4S lead-acid battery, and the power supply voltage needs to be
Between 6.5V-16V, not in this range may cause damage to the board components;
2. Connect the line according to the connection diagram. After powering on, select the appropriate capacity, magnification and
Parameter such as gear position, observe whether the indicator light 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 should be free of oil stains and protrusions.
起，oxidize. Practice on the surface of iron and stainless steel to be able to tear off the 0.1mm nickel sheet
So far, it shows that you are familiar with it and can perform welding battery operation;
4. When the battery temperature is too low, it may cause the performance of the battery to drop and preheat more than a dozen solder joints.
After that, the peak performance can be restored. It is best to use it in a warm room, recharge the battery in time, and turn off when the battery is low.
After charging, you can wake up and turn on again.
Tips:
① Welding is a technique that requires practice. The scientific principle of spot welding is resistance welding.
Tight or too loose will cause the solder joints to be weak, a successful soldering will not produce large
Measure sparks and visible light in the solder joints.
②The best technique is to lightly press the soldering pen to feel the collapse of the solder joint at the moment of current output. this
When the solder joint has enough heat, the cooling time is short, and it can work firmly for a long time.
③ Too tight or too loose will lead to weak welding or burn through, and it must be avoided.
Avoid multiple soldering to the oxide layer, and ensure that the contact surface is bright.
1. Visual inspection ④The best solder joints can be obtained with different welding strengths of 1-6 grades.
Welding principle:
This product uses a high-rate lithium battery as the power source, and uses the contact point of the spot welder to contact the substrate
Resistor melts the contact points at the moment of heat generated by the thermal effect of a large current, thereby bonding them together.
P=I^2×R Whether the welding is good or not, the pressure is very important during spot welding! ! !
The pressure is too high, and the resistance of the contact point is too small to distribute enough power.
The pressure is small, it is easy to point through the nickel sheet or the contact resistance is too large, resulting in the total current of the entire circuit
Decrease, so that the current does not go from below. Therefore, it is necessary to practice repeatedly and control the intensity, the more
The closer to that balance point, the better the spot welding effect. This product can be welded 18650/26650/326
50 lipo battery, portable, stable and reliable.
Recommended parameters:
—System voltage: 6.5V-16V (best 11.5V-14.8V)
-Working current: 100A-900A
Suggested battery:
1. The 12V-30-65ah lead-acid battery has good performance and low internal resistance (the internal resistance is less than 10 milliohms,
The electric current is greater than 100A), such as a car starting battery!
2. 4000mah-10000mah, 30-70C, 2S, 3S, 4S model airplane lithium battery
(4S battery needs to be less than 16V)
3. 30-35ah capacity 18650 battery pack
4. Battery discharge current <900A and short circuit current <1800A, exceeding this range may damage the control
board!
Operation instructions
1. Connect the positive and negative poles of the battery according to the product connection diagram.
2. The soldering pen and battery cable should be locked with fixing screws to avoid sparking and welding
Not reliable, not strong.
3. Long press the on/off button for 2 seconds to turn on the device, at this time the turn-on indicator will always be on (blue light);
4. Select the corresponding capacity (green light), magnification (blue light) and indication according to your own battery parameters
The lights will be lit accordingly;
5. Short press the gear selection (yellow light) button again to select a suitable gear for welding;
6. Find the nickel sheet, place the nickel sheet on the positive/negative electrode of the battery that needs to be welded, and the two soldering nibs
Get as close as possible, lightly touch the nickel sheet, and automatically output instantaneous pulse welding nickel after 0.5 seconds
Film; after each output, the buzzer will sound once, and then you need to remove the spot welding pen, otherwise you cannot enter
Line the second output (the purpose is to prevent the welding time from being too long and damaging the battery).
Note: Small capacity 18650 battery and DC power supply cannot be used as power supply. It must have
A high-rate lithium battery pack or car start-up lead-acid battery discharge capacity>100A!
Description of buttons and indicators
1. Turn on and off the button; long press the power button for 2S, the device can be turned on, off, and on at the same time
The indicator light will also light up or go out accordingly;
2. Capacity, rate, users can select the corresponding parameters according to their own battery parameters, and at the same time
The response indicator will light up accordingly, the capacity indicator will be green, and the rate indicator will be blue;
3. Gear button: The function of this button is to adjust the welding output power, divided into one to six
Gears, the first gear has the least power, the sixth gear is the largest, and the gear indicator is yellow;
4. Buzzer: the buzzer will sound once when the machine is switched on and off,
There will also be a reminder when, and a reminder will be sounded every time the normal welding output process;
