Features:
 * Double pulse micro-computer spot welding and battery charger, that's the first technology in the world.
 * Micro-computer control up to level 199(99x1;99x2), precision parameter setting.
 * There have one or two pulse to choose to faster welding.
 * It have two current setting to fast set welding current. The maximum up to 16 pulse, Suit for welding thicker material.
 * The charging part has 4.2V-15V to continuously regulated, it satisfied for most single and assembled battery to charge.
 * It have foot switch and pressure adjuster, that improve the accuracy of welding.
