Description of display screen of NANORIG double pulse farad capacitor spot welder: Pre-welding: the time when the MOS tube is turned on for the first spot welding, the the time is, the higher the spot welding power is. Interval: The interval between the first spot welding and the second spot welding, the greater the time, the later the start time of the second spot welding. Pulse: the conduction time of the MOS tube for the second spot welding, the the time is, the higher the spot welding power is. Note: Double pulse refers to two spot welding, pre-welding means the first spot welding, pulse means the second spot welding The small portable spot welding machines on the market now have built-in soft-pack batteries, which have too many defects, such as long-term spot welding that causes damage to the soft-pack batteries, and the batteries will be scrapped if they are not for a long time, and they need to be maintained at intervals. Quite troublesome. In response to such market feedback, we launched a spot welding machine with a built-in Farason capacity. The life of super farad capacitors is dozens of times than that of soft pack batteries. Eliminate the hassle and cost of frequently replacing pouch batteries. It also solves the long-standing problems. Plug Type: EU Plug, it applies to Indonesia, Germany, France, , Italy and so on voltage: AC220V Material: aluminum alloy colour: red black Package Contents: 1 x Handheld Spot Welder Machine 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.
