User Manual of MashWB_QB
Thank you for choosing the spot welding machine produced by BlackTechLabTM. Its weight is
only 420g. The principle is that two high rate 5Ah capacity 65C rate lithium batteries can be
discharged through the high-temperature electrode of alumina copper, which can output huge
current in a very short time, release it at the contact point between the solder pen and the
nickel sheet, produce high-temperature molten solder, and then rapidly cool down, so as to
ensure the firmness of the solder joint And light. It is suitable for battery assembly and
welding of thin iron-based materials.
Indicators:
Output voltage: 3.2-4.25v (low voltage protection shutdown)
Output current: 400-600A (varies according to welding material)
Welding capacity: 0.12mm /0.1mm pure nickel strip
Low power consumption: < 0.022ma (shut down for more than 2 years)
The outer package is in good condition. After full charge, read the following precautions
before operation
1: Function test
First of all, long press the button on the circuit board panel, and you should hear three
clear beeps, which indicates that the welding machine is on. Short press to switch gears,
there are 5 gears, which are mapped to 0-70 MS respectively, corresponding to welding nickel
strips with different thickness, and then jump to the first gear cycle after the fifth gear.
The indicator light flashes several times, representing several gears. In the start-up state,
press the button for a long time, and the "beep -" long sound will shut down. At this time,
the welding machine will not flash, sound, or consume electricity. It must be shut down after
not using it! Otherwise, it will be standby power consumption.
2: Welding test
After the above tests are passed, put the battery to be assembled stably, put the nickel
piece on the battery to be welded with the left hand, and hold the two welding pens with the
right hand like chopsticks. The welding pen contacts the nickel sheet and gently presses the
nickel plate and the battery. If it is in 1-5 gear, the circuit board will detect the contact.
After 1 second delay, the output current will be welded. At this time, it is normal to see
the dark red flash at the contact point.
3: Advanced skills
Welding is a kind of technology, which needs to be practiced. The scientific principle of
spot welding is resistance welding. If the pressure is too tight or too loose, the solder
joint will not be firm. A successful welding will not produce a lot of sparks and visible
bright concave solder joints. The best technique is to press the soldering pen lightly to feel
the moment of current output and the collapse of solder joint. At this time, the heat of
solder joint is enough, the cooling time is short, and it can work stably for a long time. If
it is too tight or too loose, the welding will not be firm or burn through phenomenon will
occur. Moreover, the oxide layer must be avoided for many times welding, and the contact
surface should be bright. With different welding strength of 1-5 gears, the best solder joint
can be obtained.
4: Maintenance
The spot welding machine shall avoid bumping and damp as far as possible, and the welding
machine shall be shut down during storage. After optimization, the power consumption of the
shutdown gear is very small, which can stand by for more than one year. The power consumption
of gear 1-5 is large. Although there is a low power shutdown function, it is still necessary
to avoid it!!
For normal use, it needs to be fully charged. The type-C charge is not divided into positive
and negative to ensure that 5V > 500mA. During charging, the indicator light turns red and
full green. At this time, it can be welded. Please pay attention to the shell temperature when
it is used for a long time. When the temperature is higher than 60 ℃, protect the power off.
In order to prolong the life of the energy storage battery as much as possible, it is not
necessary to charge the battery too full. It is enough to charge for 2-3 hours. (long term
storage)
5: Simple troubleshooting
After reading the advanced skills in Section 3, it is necessary to understand and practice
the principle of electric welding.
<Jump back to the power off gear>. It may be out of power. Charge. If the buzzer is silent
at this time, it can also be charged,
< cant charge > check whether the USB charging port is damaged and the wiring is burned.
When pulling and inserting, it should be straight and straight, and can not be pulled back
and forth.
Check whether the battery is dead, open the two welding pens, and measure the voltage with
a multimeter as the battery voltage..
The above faults may be encountered by novice players and can be easily checked. I collected
them for the reference of fans.
The welding machine has been improved for many times, the hardware and software are very
mature, normal use will not be damaged, default users read this manual. The point is to use
it as an important tool for you, not to tinker with it. If it is damaged by misoperation,
please contact me to solve the problem. If the battery and circuit board are seriously damaged,
you should pay the maintenance cost according to the situation.
