Make sure you have all materials needed to complete the job and have taken all safety precautions[...]

B-5 OPERA TION B-5 • Hold the nozzle standoff 1/8 ” (3.2mm) to 3/16 ” (4.8mm) above the workpiece during cutting. Do not let the nozzle touch the work or carry a long arc. • Keep moving while cutting. Cut at a steady speed without pausing. Maintain the cutting speed so that the arc leg is 10 ° to 20 ° behind the travel direction. • Use [...]

B-6 OPERA TION B-6 PILOT ARC DISCUSSION The PRO-CUT has a smooth, continuous pilot arc. The pilot arc is only a means of transferring the arc to the workpiece for cutting. Repeated pilot arc starts, in rapid succession, is not recommended as these starts will generally reduce consumable life. Occasionally, the pilot arc may sputter or start intermi[...]

B-7 OPERA TION B-7 Suggestions for Extra Utility from the PRO-CUT System: 1. Occasionally an oxide layer may form over the tip of the electrode, creating an insulating barrier between the electrode and nozzle. This will result in the tripping of the Pro-Cut's safety circuit. When this happens turn the power off, remove the nozzle and electrode[...]
