section 3INstallation3.1.2 Connection of Gas Hoses1 - Female old-style air water nut for Shield Gas connection.12 - B-IG fittings for Plasma Start gas and Plasma Cut gas.Either hose can be attached in either location.23.2 Mounting Torch to MachineRefer to machine manual.cautionClamping on Torch Body May Cause Dangerous Current To FlowThrough Machine Chassis.Mount torch on insulated sleeve hereDO NOT mounton steel torchbody here• Do not mount on stainless steel torch body.• Torch body is electrically insulated, however high frequencystart current may arc through to find a ground.• Clamping near torch body may result in arcing betweenbody and machine.• When this arcing occurs, torch body may require non-warrantyreplacement.• Damage to machine components may result.• Clamp only on insulated torch sleeve (directly above label)not less than 1.25" (31.75mm) from the torch end ofthe sleeve.144
section 4operationWARNINGOil And Grease Can Burn Violently!• Never use oil or grease on this torch.• Handle torch clean hands only on clean surface.• Use silicone lubricant only where directed.• Oil and grease are easily ignited and burn violently in the presenceof oxygen under pressure.WARNINGHydrogen explosion hazard.• Do not cut under water with Hydrogen gas!• Hydrogen explosions can cause personal injury ordeath.• Hydrogen can create explosive gas pockets in the watertable. These pockets will explode when ignited bysparks or the plasma arc.• Before cutting, be aware of possible hydrogen sourcesin the water table – molten metal reaction, slowchemical reaction and some plasma gases.• Explosive gas pockets accumulate underneath thecutting plate and inside the water table.• Clean slag (especially fine particles) from bottom oftable frequently. Refill table with clean water.• Do not leave plate on table overnight.• If water table has not been used for several hours, vibrateor jolt it to break up hydrogen pockets beforelaying plate on the table.• If possible, change water level between cuts to breakup hydrogen pockets.• Maintain water pH level near 7 (neutral).• Programmed part spacing should be a minimum oftwice the kerf width to ensure material is always underthe kerf.• When cutting above water, use fans to circulate airbetween plate and water surface.WARNINGExplosion Hazard.Do Not Cut Underwater With H-35! Dangerous buildup ofhydrogen gas is possible in the water table. Hydrogen gasis extremely explosive. Reduce the water level to 4 inchesminimum below the workpiece. Vibrate plate, stir air andwater frequently to prevent hydrogen gas buildup.145
