The TIG-Pen® is the first manual welding wire feeder that truly makes sense. You operate the comfortable TIG-Pen by holding it in either hand like an ordinary pencil. With the touch of your finger, you feed TIG wire (filler rod) into the puddle. The TIG-PEN works with any diameter wire from .030" to .125" and gives you the ability to use virtually all of the welding wire. Lightweight, compact, and allows your hand to rest on the work piece. The TIG-PEN gives you total control of the filler material and helps create a better quality weld.
