1. Gear 99 power regulation, nixie tube real-time gear display, gear 0-99, gear 1 is the lowest, gear 99 is the highest, and gear will be increased in turn when using 2. Real time voltage monitoring protection, if the voltage is not within the range of 8-17V, UE alarm code will be displayed 3. Real time MOS tube temperature protection. If the MOS tube temperature exceeds 45 degrees, alarm code will be displayed 4. Bilateral outgoing line is convenient for spot welding, and the product is marked to avoid wrong connection 5. Five MOS tubes are used, and five MOS tubes are used for the spot welding machine control board. After five MOS tubes are connected in parallel, the theoretical maximum current can reach about 1500A Product name: 99 grade spot welder Product model: Z99 Working voltage: 8V-17V Working current:Less than 20ma Standby power consumption:Less than 0.5 ma Thickness of welded nickel sheet: 0.1-0.2mm (related to battery discharge energy) Welding current: 1500A MAX Product size: 89 x 54mm color:Blue Material:PCB+metal Package Contents: 1 x Spot welding 2 x input line 2 x spot welding pen 2 x heat shrink sleeve 1 x screw pack 1 x Nickel sheet Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
