An improved holder for a carbon arc electrode has a tubular handle that receives an electrical conductor and a hose for conducting air under pressure. An insulation block is affixed to the forward end of the tubular handle. A metal torch body extends from the insulation block in the direction opposite the handle and is in electrical communication with the electrical conductor. A flow passageway opening is provided within the body. An electrode support is affixed to the body and has a concave electrode contacting surface that is inclined at an angle to the torch body and has a lower surface having a gas passageway recess therein communicating with the torch body flow passageway. A U-shaped bail extends from the insulation block and has a bight portion positioned laterally above the electrode contacting surface. An insulation sleeve is received on the bight portion to engage an electrode positioned on the support by which the electrode is held in place so that a workman can establish an electrical arc with a metal work piece to melt away portions of the work piece, the molten metal being blown away by air passing through the handle and the electrode support air passageway.
