Lotos Technology LTP5000D Quick Setup Instructions Power plug wiring identification: The GREEN wire with the yellow strip is ground wire. The other two wires have equal usage. They are both hot wires for 240 V. And one is hot one is netural under 120 V. Quick Setup: 1. Wear a proper helmet (Figure 1.1) to protect your eyes from harmful plasma cutting arc radiation. Wear safety gloves to protect your hands during operation. Figure 1.1 2.
3. Connect your plasma cutting torch and ground cable to the front panel of the machine (Figure1.5). Air/Power Output 3-pin Switch Plug Ground Cable Figure 1.5 4. Attach the ground clamp to the metal work piece that you plan to cut. Make sure that you cannot pull out the ground connection from the machine input. The metal work piece should be securely attached. 5. Make sure the consumables are properly assembled on the torch head. 6.

Introduction Overview Dear Valued Customer: Thank you for purchasing a Lotos Technology plasma cutter! Feel free to check out our other products at www.uwelding.com. The User Manual documents policies and procedures for proper operation of the equipment. IMPORTANT: Be sure to review the contents of this manual before attempting to operate the equipment. This manual should be located where it can be easily referenced by all users of the machine.
Safety Recommendations - Read Before Using Overview Protect yourself and others from injury — read and follow these precautions. Caution Recommendations • Connect the machine to a UL-approved outlet only. Do not hard wire the machine directly to the power source. • Wear safety goggles at all times. This will darken the arc that is generated by the machine and protect your eyes from harmful rays. • All machine operators should be technically certified for welding/cutting.
Welding or Cutting can cause Fire or Explosion. Welding, cutting, and allied processes can cause fire or explosion if precautionary measures are not followed. • Develop adequate procedures, and use proper equipment to do the job safely. • Remove combustible materials from a sphere with a minimum radius of 35 feet around the work area or move the work to a location well away from combustible materials. Burn Protection: HOT PARTS can cause serious burns. The work piece and equipment get hot.
California Proposition 65 Warnings For Gasoline Engines: Engine exhaust contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Section 25249.5 et seq.
Equipment General Overview The LTP5000D employs state of the art inverter technology. 50/60Hz frequency is inverted to high frequency (over 100 KHz) by V-MOSFET followed by step down voltage and rectification current. Using Pulse-Width-Modulation (PWM) technology, the inverter power supply generates powerful DC welding currents. By applying switch power inverter technology, the dimensions and weight of the main transformer is significantly reduced; while efficiency is increased by 30%.

Installation Power Cord Plug Connection (Figure 2.2) 1. Be sure to connect the power cord plug to the appropriate power voltage and use a proper hookup to avoid damage to internal circuitry. Typically, the ground wire is GREEN with a YELLOW stripe. 2. Ensure that the power cord is properly connected to the power switch to prevent oxidation. Make sure the power voltage is within the specified safety range. 3.
Operating the Plasma Cutter 1. Adjust the air pressure on your air compressor to 60 – 65 psi for the machine. 2. Bring the torch tip into direct contact with your work piece edge or, for thicker cutting, over a pre-drilled pilot hole. Press the button on the torch to start cutting. 3. Ensure that the cutting current is appropriate and adequate for the machine based on the rated thickness of the cutter. Note: Below is the consumable assembly on the torch head (Figure 3.1).
Instruction Notes Cutting Environment 1. The cutting machine can perform in an environment where conditions are particularly harsh: it can withstand outside temperatures between 14 and 104 degrees Fahrenheit and a humidity level of up to 80%. 2. Please try to keep machine dry. Safety 1. Working area MUST be adequately ventilated. 2. No over-load! Your machine can be damaged by over-loading. 3. No over-voltage! Internal circuitry can be damaged by over-voltage. 4.
Plasma Cutter LTP5000D Troubleshooting Flowchat Note: If the O.C. light turns on before operating the machine, please call us at (408) 739-2329. If the O.C. light turns on while operating the machine, please let the machine take a rest, as this is normal operating procedure.

1.1 Plasma Cutter LTP5000D Connections First make sure all the connection are corrected (as depicted in the diagram below); Set the air compressor's PSI at 65 PSI.
1.2 Plasma Cutter LTP5000D FAN TROUBLESHOOTING If machine powers on but you cannot hear the fan running and you can strike an arc then try the following steps: Turn off the machine and pull the plug from the socket. Try to open the machine: a) Check the cable connected to the fan on the bottom board. Highlighted in red. Make sure it is tightly connected. b) Then power on the machine, to see if the fan works or not. c) If problem remains, with this step you need to be very careful, since the power is on.
