The length of electrode extending beyond the end of the contact tube.
Welding Tech
The steel wire about which the coating is applied. The electrode size is determined by the diameter of the core wire.
The mixture of chemicals, minerals and metallic alloys applied to the core wire. The coating controls the welding current, the welding position, and provides a shielding atmosphere, deoxidizers to clean the weld metal, and the welding slag that absorbs impurities from the weld metal. It also helps shape the weld bead and becomes an insulating blanket over the weld bead.
The plasma arc torch part from which arc current is emitted.
In any welding process using a solid or flux cored wire, the electrical stick-out is the distance from the contact tip to the un-melted electrode end. Sometimes called the ?amount of wire in resistance?. This distance influences melt-off rate, penetration, and weld bead shape.
