Description Lithium battery advantages portable stable and reliable and durable Users need to supply 12V battery power welding current is about 90A 150A for the common 18650 26650 32650 0 1mm 0 15mm nickel plated welding After several generations of product updates it is now upgraded to automatically trigger the welding liberating the buttons of the fingers Switch function press the switch for 1 5 seconds to switch blue light low p0wer green light medium power red light high power Power supply requirements System voltage 12V 14 6V It will stop 12V Current requirements 150A or more instantaneous output such as car starter power supply 3S RC high power battery pack 20A lead acid battery with good performance above 20A Misunderstanding Don t think that you can use 3 series 18650 series to supply power After all the conventional 18650 only has 3 5C discharge rate so each section can only provide 2 5A 3 7 5A load capacity which is far from 150A unless 20 Parallel connection 3 series and 60 sections of 18650 are possible but it is obviously unrealistic Features 1 it is equipped with a 3 7 4 2V 4 5ah power lithium battery with a discharge rate of 100C and a load capacity of about 400A 2 Through the MOS tube output this energy will be concentrated at the end of the welding pen and it will be heated by short circuit 3 Fuse the nickel sheet firmly with the battery All this will happen in milliseconds And it is precisely controlled by the single ch
