The forceful are renders it possible to chamter and gouge various away run wan teal metal from its leaving a clean groove for subsequent laying of weld for surfacing, rebuilding etc. Mark the area to be gouged whit chalk. Hold the electrode pointing towards the part of gouging at an angle not exceeding 25 0 to the job push the electrode along the line maintaining contact with base metal all the while. The strong arc force produced by the electrode and pushing action will below the molten metal ahead and away from groove. Avoid reverse motion. Procesure: Mark the area to be gouged white chalk.hold the electrode pointing towards the part of gouging at angle not exceeding 25 0 C to the job push the electrode along the line maintaining contact with base metal all the while. The Strong arc force produced by the electrode and pushing by the electrode and pushing action will below the molten metal ahead and away from groove.avoid reserve motion mm 4.0 mm 5.0 mm
