LOTOS TECHNOLOGY Plasma Cutter TIG Stick Welder LTPDC2000D www.uwelding.
Lotos Technology LTPDC2000D Quick Setup Instructions Power plug wiring: For either 110 or 220VAC, the GREEN wire is the ground wire. The WHITE and BLACK wires are hot wires. For Plasma Cutting: 1. Wear a Lotos auto darkening plasma cutting helmet (Figure 1.1, not included in the box. To purchase, please go to our website.) to protect your eyes from harmful plasma cutting arc radiation and safety gloves to protect your hands during welding. Figure 1.1 2.
. Connect your plasma cutting torch and ground cable to the front panel of the machine. Make sure the ground cable is connected on the right hand side where the “+” sign is located. (Figure 1.4) - Set TIG Weld /Stick Weld /Plasma Cut - Set “2.5S/5S” to “2.5S” mode. - Set “Machine/PEDAL” to “Machine” mode. - Adjust current dial between 10 and 50 amps. to Plasma Cut mode.

15-20 min/L Output from Air Compressor Gas Inlet Argon Regulator Figure 1.5 Figure 1.6 Argon Gas a) If you switch from plasma cutting to TIG welding quite often, consider buying a LOTOS 3 way valve kit to connect both the argon tank (Figure 1.7) and the air compressor simultaneously. Machine Air Compressor Figure 1.7 - Connect your TIG torch and ground cable to the front panel of the machine.
b) If you want to dynamically control the welding heat, please use a foot pedal (not included in the box. To purchase, please go to our website). Then connect the “on/off” connector to your foot pedal and leave the wire of the TIG torch unplugged. - Set TIG Weld/Stick Weld/Plasma CUT to TIG Weld mode (refer to Figure 1.4, page 2). - Set “2.5S/5S” to “2.5S” mode. - Set “Machine/PEDAL” to “Pedal” mode. - Adjust current dial between 10 and 200 amps (Figure 1.9).
For Stick/Arc/MMA Welding: 1. Wear our auto darkening welding helmet and gloves to protect your eyes and hands from any harmful welding arc. (Please see step 1 in Plasma Cutting.) 2. You don’t need to connect the machine to any gas or air supply. It’s a plug and play. Panel connection instructions: - Set TIG Weld/Stick Weld/Plasma Cut to Stick Weld mode (refer to Figure 1.4, page 2). - Set “2.5S/5S” to “2.5S” mode. - Set “Machine/PEDAL” to “Machine” mode.

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. This 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 Precautions - Read Before Using Overview Protect yourself and others from injury — read and follow these precautions. Caution Recommendations CAUTION: Welding and arc cutting can cause bodily injury. • Do NOT switch off the machine while machine is in operation for internal circuitry can be damaged. • 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.
Welding or Cutting can cause Fire or Explosion. Welding, cutting, and allied processes can cause fire or explosion if precautionary measures are not followed. • 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. • Develop adequate procedures, and use proper equipment to do the job safely. Burn Protection: HOT PARTS can cause serious burns. The work piece and equipment get hot.
Equipment General Overview The LOTOS LTPDC2000D is a first to market multi-process welder that allows the user to DC TIG/ STICK and Plasma Cut all from one portable machine.
