NO pen do spot welding ------ No ma need to use pen do spot welding when you go out or at home, manual spot welding machine that does not require additional pens do spot welding, carry it with you and it is convenient to go anywhere. It combines a built-in power supply and a welding pen, making it easy to weld without the need for an external welding pen. Widely used - suitable do cylindrical batteries, such as 18650/26650/36650, do batteries of mobile phones and electronic devices requiring batteries. The spot welding machine can be used do electronic devices that have been damaged as a result of battery damage, replace the battery and resume operation (as in the case of manual electric drills), saving money and protecting the environment. Easy to use - only 2 buttons, our spot welding machine, buttons are marked, easy to use. The cordless spot welding machine does not have to leave our hand. Press and hold the middle finger for 2 seconds the power switch button on the side, press the gear adjustment button on the top with your index finger once, then press and hold for 2 seconds to adjust the automatic or manual mode. 11 adjustable gears - Spot welding machine ma 11 adjustable output powers, which can be adjusted according to different point-welded materials. Mobile phone battery 1-3 gears, 3-6 gears nickel plate 0,1 mm, 6-11 gears 0,12-0,15 nickel plate. One charge allows you to perform spot welding more than 200 times. Many protective measures - this is a mini manual spot welding machine,but ma high quality polymer cells,overcharge protection, temperature protection,short circuit protection, alarm of abnormal battery temperature and spot welding function and alarm of low cell voltage. Very low power consumption, longer standby time. Exquisite packaging - our package includes a manual spot welding machine, 2-meter nickel-plated sheet, 1 piece of matte paper, 1 Type-C charging cable and an instruction manual. Our packaging is very exquisite, making it a very valuable gift for a loved one who loves tinkering with batteries and friends. How to use manual mode On the side there is a manual spot welding machine mode button, which is an "ON/OFF key" First, press and hold “Key ON/OFF” for 2 seconds, Then press and hold the top “shift key” for more than 2 seconds, and the indicator light will go do manual mode. Then press the top “Gearshift key”, material 0.1, and you can use the minimum gear do exercise. Then add the gears to see the effect and choose the one that you think is best. Then proceed do spot welding, in which the tip of the pen do spot welding completely contacts the material. Pressing the “ON/OFF” button will cause one-time spot welding. The reason we designed the side buttons of manual mode is because of their ergonomics. Make it easier to operate manual mode.

Product Specifications: Model : H1 Mode: 11 adjustable gears Charging interface: type C Charging parameters: 5V/1A Working voltage: 4,2 V Output current: 650A Size product: 43*25*192 MM Package Contents: 1 * spot welding machine 1 * Nickel Plate 1 * do data cable 1 * matte paper Please note Point welding angle: During spot welding, it is recommended to incline the spot welding angle by 30, which gives an angle of 60 do spot welding, this angle is better. Point welder contact location: In the case of spot welding matching, both point welding points must come into contact with the material at the same time, not one spot welding, and the other not. When both pens come into contact, a spot welding current will be generated and a spot welding reaction will occur. The material of the spot weld should be smooth: During spot welding, care should be taken to ensure that the spot welding of the material is smooth and clean. Spot welding of the matching 18650 battery must be laid flat on the battery. The battery and material must not have a gap, if there is a small gap, use the do spot welding pen to gently press the following elements so that the battery and material have a full kontakt.
