Thank you for choosing the spot welding machine produced by BlackTechLab
TM
. 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.
