DETAILS
For preparing sections prior to welding, gouging out old or defective weld metal, removing flash and risers.
Features
- All these operations can be carried out in all positions; except vertical upwards.
- A thick, specially developed exothermic coating produces a forceful gas jet which blows the molten metal away, to give a smooth, clean groove. A finishing operation is unnecessary.
- Strike the arc with the electrode normal to the workpiece and then immediately incline the electrode at an angle of 15-20° to the workpiece.
- Point the arc in the direction of travel, move the electrode forward to melt the metal and then pull it back to allow the gas jet to blow the molten metal away.
