HF Pilot start – Enables easy arc start even on painted surfaces 4. HF pilot arc restart – ideal for cutting mesh etc 5. Digital amp meters 6. Quick fitting torch for easy torch fitment/replacement 7.
Safety Precautions Read entire section before starting installation WARNING! Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input power at the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine to an earthed mains supply as per national recommended standards. Select suitable location Place the plasma cutter where clean cooling air can freely circulate in and out of the front & rear louver vents.
Electrical Installation WARNING! ELECTRIC SHOCK CAN KILL Machine grounding and High Frequency Interference Protection This plasma cutter must be grounded to earth. See national electrical codes fro proper grounding methods. The high frequency generator being similar to a radio transmitter may cause interference to radio, TV and other electronic equipment. These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate this.
smaller than recommended will result in ‘nuisance’ shut off from welder inrush currents even if cutting at low amperages. Failure to follow these instructions can cause immediate failure within the welder and void machines warranty. Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have a qualified electrician install & service this equipment. Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment.
Connections for Plasma 60HF Rear Machine connections Fig 1 1. Air pressure regulating knob This regulates the air pressure as displayed in gauge on front of machine. To adjust pressure pull knob upwards and turn to adjust pressure, once correct pressure is obtained press down knob to secure. 2. Air pressure input Screw supplied PCL fitting into regulator ensuring no air leaks You can also fit other connectors to suit your needs 3.
- Not normally used 4. Mains input cable Fit required plug as per your electrical installation 5. On / Off Switch Turns machine On / Off Front machine connections Fig 2 1. Earth / Workpiece connector Connect the earth lead (negative - ) to this connector. Insert male connector into socket and twist clockwise until tight. Secure other end of earth lead to Workpiece via the earth clamp. 2. Fuse holder – Pilot Arc Protection Protection fuse for pilot arc start 3.
5. Torch power connector Connect the main torch cable by screw clockwise until tight. Controls and Settings Fig 3 1. Air pressure gauge This shows the air pressure as set by regulator at rear of machine. This should be set to 55PSI when the test gas button is activated. 2. Amperage control knob This adjusts the amperage (cutting power) from 20 to 60 amps Note: LED display will show cutting amperage when you are cutting 3. L.E.
When in the up position this is in auto mode, this is for special applications when using automated machinery. Not normally used Operating machine SAFETY PRECAUTIONS WARNING! ELECTRIC SHOCK CAN KILL Do not touch electrically live parts or electrode with skin or wet clothing. Insulate yourself from work and ground Always wear dry insulating gloves WARNING! FUMES AND GASES can be dangerous Keep your head out of fumes & gases produced from welding.
Operating Machine Please ensure all torch consumables are tight before use 1. Ensure machine has been setup as previously stated 2. Turn on the machine and the power light indicates and cooling fan is running 3.
If you ever have any questions on settings call us and speak to one of our experienced technicians who will be happy to help you. Replacing torch consumables WARNING! ELECTRIC SHOCK CAN KILL Please ensure machine is turned off before changing consumables If cutting performance is poor you probably need to check / change the torch consumables. To change the plasma cutting consumables carry out the following procedure 1. Switch off machine 2. Ensure torch has cooled down to avoid burns 3.
Maintenance Routine and periodic maintenance WARNING! ELECTRIC SHOCK CAN KILL Turn the input power OFF at the mains switch & fuse box and remove mains plug from socket before working on this equipment. Have a qualified electrician install & service this Plasma cutting equipment. Allow machine to sit for 5 minutes minimum after disconnection from mains power to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically live parts 1.
FAULT DIAGNOSTICS 1. Power light not lit Check machine on/off switch is in the ‘on’ position Check Input power to machine Check plug wiring Check mains trip / fuses 2. No output - Fan runs - Power light is lit Check torch connections are secure and torch switch operation, try replacing plasma cutting torch 3. No output - Power light is lit - Warning light is lit Welding application may have exceeded recommended duty cycle, allow machine to cool down until the warning light goes out. 4.
air supply. Check for adequate ventilation around machine 6. Erratic cut – Torch spitting when cutting Check torch consumables and replace if necessary as per instructions earlier in this manual Check if correct amperage for thickness of metal, if to slow travel speed or to much cutting power, increase speed of cut or reduce cutting amperage.
