Code: PPT31-4
The PT31 Short electrode is a copper coated, double sided spare that delivers the electricity to the work piece. Once worn down, this electrode can be turned around and reused as a new electrode. Life expectancy of this consumable depends on the operator of the torch. When arcing occurs, ensure that the torch is slightly angled away from the material to be cut to allow the molten metal an escape route, ie; away from the torch head to minimize blow back into the nozzle. If piercing is required and the torch is held at 90 deg straight down onto the job then it would cause blow back into the torch head which would require more frequent changing of consumables.
The short electrode is often preferred by operators who are using a length of angle iron as a straight edge as the shield cup is close enough to ensure the short nozzle doesn’t arc on the metal angle iron.
