Includes Line Welder Controller, 1 head, 3 welding cartridges, USB power supply, 12 micro USB charging cable to attach hooks and lures with ease. The Tauten LineWelder is a handheld, battery-operated device that bonds 10-12 lb test monofilament, 10-12 lb test fluorocarbon and 10-50 lb test braid lines in less than a minute. Loop size allows for free movement of the hook or lure and there is no weed pick-up because of the smooth shape and finish. Trim the tag end flush with the Tauten LineCutter for an even slicker result. The molded-in-place polymer sleeve produces a strong joint that does not decrease available line strength. The weakest point in a conventionally knotted line is the knot. Even the best tied knots will often fail before ultimate line strength is achieved whereas the joint produced by the Tauten LineWelder exceeds line strength. Designed to resist ingress of dirt and water, the LineWelder is at home in your shop or in your tackle box. The integrated lithium-ion battery provides 150+ welds per charge.
