1: Built-in 6*300A high-power MOS tube, with margin and low failure rate 2: Spot welding pen adopts ec5 plug, 30cm 8awg wire, 6mm diameter solid aluminum oxide copper rod length 10cm, the whole welding is non-pressing, and the internal resistance is lower than other hand- spot welding machine on the market, so the support current is larger. Spot welding with thick is stronger 3: 20-speed delay time adjustment, 0.5s-2.5s; 20-speed power adjustment, with memory, automatic shutdown in 5 minutes. 4: We have already equipped the type-c charging cable, prepare an ordinary 5v2a charger for charging by yourself, you can check the charging current on the screen : In the shutdown state, short press 0N/0FF (red button) to turn on and use the spot welder function Shut down: In the power-on state, press and hold the 0N/0FF (red button) to turn off the machine, and the machine also has the automatic shutdown function of 5 minutes without operation Adjust the delay: In the power-on state, press (red button) until the delay number is highlighted, and then press V+/V- (black button) to adjust the delay time. The range is 0.5 seconds-2.5 seconds. This time determines the contact of the soldering pen to be welded Automatic spot welding of metal starts to delay for a period of time Adjust spot welding power: In the power-on state, press (red button) until the power number is highlighted, and then press V+/V- (black button) to adjust the power range. The range is 1-100. The larger the number, the higher the spot welding power. , adjust appropriately Colour:gold Material:ABS Package Contents: 1x 5300mha Spot Welding Machine Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
