Product Specification


1. Please do not change the wiring settings arbitrarily. If the lithium battery is used for power supply, the charging MOS may be damaged. In addition, failures caused by modification are not the seller†s responsibility.
2. Please note that when inserting the screen after receiving the goods, please check that the screen pins and holes correspond one by one, and then plug in the charger, otherwise the control board will be directly damaged.


1. Using 2.7V 100F or 120F capacitor with very low internal resistance, 2 series 8 parallel, Internal resistance: 5 milliohms, a total of 400F, not 1600F.
2. Using 25 square soft AWG silicone wire, lower internal resistance and good feel.
3. It adopts red copper threaded soldering pen, which has lower internal resistance and more durable than traditional brass soldering pen.
4. The control panel has been updated with new functions, we will always release new versions, so stay tuned.
5. This product is assembled and finished. It can be used directly after receiving the goods.
6. Added voltage 1 and voltage 2 display functions to control the voltage during spot welding.
7. Voltage: AC220V, Power: about 60W
8. Main body: 11x11x10cm, Soldering pen: 50cm
9. Welding thickness: recommended within 0.25mm

The use of the machine:

Connect the charger, the lower right corner is the rotation button, the rotation can move the cursor and adjust the value size, and the confirmation is to press the button.
1. The larger the value of the pulse, the stronger the welding ability. For example, the value of pulse one for spot welding 0.15MM nickel is about 7, and the pulse two can be adjusted.
Wait: Simply put, the larger the continuous discharge value, the longer the continuous discharge time.
Automatic welding: It can be adjusted according to your own requirements ... (Novice recommends more than one second)
2. The voltage setting in the interface can adjust the voltage discharge voltage of the capacitor, for example: the capacitor is a single 2.8V, then the voltage is 5.6V after the series connection, if the capacitor is 2.7V, it is 5.4V adjustable, remember not to exceed the voltage after the series!
3. System setting:
(1)The charging current refers to the charging speed at which the capacitor is charged, the larger the value, the faster the charging, the value range is 1-10A
(2) Single capacitor withstand voltage: refers to the withstand voltage range of a single capacitor, such as 2.7V withstand voltage and 2.7V capacitor. This is safe. The 2.8V capacitor is set to 2.7V. This is not overvoltage and long-term use Will cause damage to the capacitor
Do not set a voltage value that exceeds the capacitance! Save and exit after making data changes!
4. E.g:
Spot welding 0.15 nickel sheets setting: pulse 1 is 5ms, pulse 2 is 5ms, and AUTO is 1S.
Spot welding 0.2mm nickel settings: pulse 1 is 12ms, pulse 2 is 5ms, AUTO for 1S
It is recommended that pulse1 and pulse2 be set within 20ms to keep the spot welder healthy

Package includes:

1 x Spot welding machine host
1 x Disassembly of welding pen
1 x 12V 10A Power supply (US plug)
