PT-36 Mechanized Plasmarc Cutting Torch Instruction Manual

section 4cautionoperationRecommended cutting speed and arc voltage will give optimal cuttingperformance in most cases. Smallincremental adjustments maybe needed due to material quality, material temperature and specificalloy. The operator should remember that all cutting variables are interdependent.Changing one setting affects all others and cut qualitycould deteriorate. Always start at the recommended settings.Top DrossAppears as splatter on top of material. Usually removes easily.• Cutting speed fast• Standoff high (arc voltage)Intermittent DrossAppears on top or bottom along kerf. Non-continuous. Can appear asany kind of dross.Side ViewSplatter•Possible worn consumablesOther Factors Affecting Dross;Cut Face•••Material temperatureHeavy mill scale or rustHigh carbon alloyscautionBefore attempting ANY corrections, check cutting variables with thefactory recommended settings/consumable part numbers listed inthe Process Data.4.2.6. Dimensional AccuracyGenerally using the slowest possible speed (within approved levels) will optimize part accuracy. Select consumables to allowa lower arc voltage and slower cutting speed.noticeRecommended cutting speed and arc voltage will give optimal cuttingperformance.Small incremental adjustments may be needed due to material quality,material temperature and specific alloy.
