Embodiment Construction

[0019] Referring to FIG. 1 , an exemplary portable MIG arc welding system 12 is shown. However, the technology is also applicable to other types of arc welding systems, such as stationary systems and submerged arc welding systems. The illustrated embodiment includes a power supply / feeder 14 having a wire spool 16 . The power supply / wire feeder 14 receives an electrode wire 18 from a wire spool 16 and guides the electrode wire 18 into a welding cable 20 of a welding gun 22 . However, this technology is also applicable to welding tools other than welding torches, such as welding robots.

[0020] In the illustrated embodiment, electrode wire 18 is tubular and made of metal. Particulate flux may be placed within the tubular metal electrode wire 18 . The welding cable 20 has conductors for powering the welding torch 22 from the power supply / wire feeder 14 . In this embodiment, the power source and wire feeder are combined. However, the power supply and wire feed unit can also ...

Abstract

According to one aspect of the present technique a novel ceramic contact tip extension is featured. The ceramic extension may comprise a zirconium-based material. According to another aspect of the present invention, a novel wire-feed welding system is featured. The welding system may feature an electrical power source, a wire-feeder having a wire electrically coupleable to the electric power source, and a welding implement adapted to receive a tubular metal wire from the wire-feeder. The welding implement has a contact tip and a contact tip extension. According to yet another aspect of the present technique, a method for protecting a contact tip is feature. The method comprises thermally insulating the contact tip.

Description

technical field [0001] The present invention relates generally to welding systems, and more particularly to a wire feed welding appliance having an insulator to protect the contact tip. Background technique [0002] Welding is a method that can be used to join or separate metal pieces. A typical one of the welding processes is arc welding. Arc welding systems typically include a power source connected to the welding implement. One electrode is wired and electrically connected to a power source through the welding implement. Also, a conductive cable is clamped to the workpiece and wired back to the power source. When the electrode approaches or touches the workpiece, an arc is created between the electrode and the workpiece. Electricity flows from the power source through the electrodes to the workpiece and back to the power source through the conductive cables. The heat generated by the arc melts the workpiece or workpieces. When the arc disappears, the molten metal co...
