Use of respiratory equipment is recommended. Eye Protection The brass crown sufficiently screens off direct ultra-violet rays, so protective eyewear with lenses and side shields shade A6 is sufficient protection. This also applies when cutting with the torch directly on the work. When preparing weld edges and gouging the eyes are directly exposed to ultra-violet rays. For this type of work wearing a welding helmet with lenses shade A9 is strongly recommended. 12 Fire Prevention Hot slag or sparks can cause fire when getting in contact with combustible solids, liquids and gases. Fuel, lubricant and solvent containers must not be cut, even when they are empty. The same applies to hollow spaces containing combustible materials. - Remove all inflammable and combustible material from the work area. 3 Specifications 600 DP 900 DP 1200 DP Mains voltage: 3-380/415V 50/60 Hz 3-380/415V 50/60 Hz 3-380/415V 50/60 Hz or or or 3-230 V 50/60 Hz 3-230 V 50/60 Hz 3-230 V 50/60 Hz Input capacity: 380/415 V: 14 kVA 380/415 V: 25 kVA 380/415 V: 30 kVA 220 V: 14 kVA 220 V: 25 kVA 220 V: 30 kVA Step 1 Step 2 Step 1 Step 2 Stepl Step 2 No-load voltage: 215 V 255 V 195 V 325 V 203 V 307 V Open circuit voltage: 110V 95V 96 V 90 V 110V 88 V Cutting current: 45 A 60 A 45 A 90 A 60 A 120 A Current draw: 14 A 21 A 12 A 39 A 16 A 46 A Duty cycle: 75 % 50 % 75 % 50 % 75 % 50 % cos phi: 0.67 0.61 0.45 0.45 0.45 0.45 Insulation class: F F F Protection class: IP 21 IP 21 IP 21 Cooling: F F F Mains fuse, time-lag: 20 A 35 A 50 A Cut capacity steel: max. 12 mm max. 22 mm max. 35 mm Cut capacity aluminium: max. 8-9 mm max. 15 mm max. 25 mm Air consumption: ca. 120 Itr/min ca. 200 Itr/min ca. 200 Itr/min Air pressure required: 4.5 - 5 bar 4.5 - 5 bar 4.5 - 5 bar Water vapor at 20 °C: max. 30 % max. 30 % max. 30 % Air oil contents: max. 0.01 mg/m3 max. 0.01 mg/m3 max. 0.01 mg/m3 Dimensions Ixwxh: 650 x 570 x 370 mm 750 x 800 x 510 mm 750 x 800 x 510 mm Mains voltage: Input capacity: Stepl 1204 DP 3-380/415V 50/60HZ or 3-230 V 50/60 Hz 380/415 V: 30 kVA 220 V: 30 kVA Step 2 Step 3 Step 4 No-load voltage: 307 V 307 V 307 V 307 V Open circuit voltage: 110 V 110 V 95 V 88 V Cutting current: 30 A 60 A 90 A 120 A Current draw: 11,5 A 23 A 34,5 A 46 A Duty cycle: 100 % 100 % 90 % 75 % cos phi: Insulation class: Protection class.

This results in considerable power saving when cutting thin plate. The cutting range, from thin plate to a max. of 35 mm material thickness, makes this model the ideal choice for situations where material of different thickness is regularly worked with. All electronic components are specially protected from dust and moisture. 13 4 Operation Torch lead Overload control Current selector step 1 = 30 A step 2 = 60 A Insufficient air supply indicator Switch ON/OFF Earth cable socket Overload indicator Switch ON/OFF Insufficient air supply indicator Euroconnector for torch lead Current selector step 1 = 30 A step 2 = 60 A step 3 = 90 A step 4 = 120 A Earth cable socket Pic. 1 - Model 600 DP Pic. 2 - Model 1204 DP Euroconnector for torch lead Current selector step 1 = 60 A step 2 = 120 A Overload indicator Insufficient air supply indicator Switch ON/OFF Earth cable socket Pic. 3 - Model 900 DP/1200 DP Pic. 4 - Rearview models 600/900/1200 DP Pic. 5 - Rear view model 1204 DP 14 Principle of Plasma Cutting Plasma cutting is an arc-cutting process involving the constriction of the arc. This mechanical constriction,by means of the cutting tip with a very small orifice, causes the gas to heat up to extremely high temperatures (up to 25000°C) so that its molecules disintegrate and some of the electrons are split from the atom. This ionizes the gas and it becomes electroconductive, a state which is referred to as plasma. This plasma beam quickly vaporizes metal and its high kinetic energy effectively ejects the melted material from the kerf. 5.1 Pilot Arc The pilot arc makes cutting painted or coated material simple, without the need to clean the surface for good electrical conduction. The pilot arc is ignited between the torch's electrode and the cutting tip by high frequency. The cooling gas blows the pilot arc from the tip as a needle-shaped flame, which burns through the paint or coating. The main arc can then start between the work and the electrode. 5.2 Taking the Machine into Operation 1. Attach the male connector (torch side) to the female one (machine side). Make sure that the positioning pin (A) alig...
