not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal. v FUMES AND GASES can be dangerous Ø Plasma cutting may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When cutting, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.

Ø Never allow any electrically “hot” parts to touch a cylinder. Ø Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. Ø Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
GENERAL DESCRIPTION The LOTOS LTP8000 Plasma Cutter is one of the most powerful plasma cutters in the market. The pilot arc feature is especially useful for continuous cutting on rough surfaces or dirty metal. It has been redesigned to...
Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. Production cutting thickness are the results of LOTOS's laboratory testing. Production speeds are approximately 80% of maximum. For optimum cut quality, cutting speeds may vary based on different cutting applications.
v REAR CONTROL PANEL The unit is connected to the supply even if the Power Switch is in the “OFF” position, and therefore there are electrically live parts inside the power source. Carefully follow the instructions given in this manual. REAR CONTROL PANEL Power Cord Unit Power Switch...
Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown. Ø STACKING LTP8000 cannot be stacked. Ø TILTING Place the machine directly on a secure, level surface. The machine may topple over if this procedure is not followed.

1. Direct interference radiated from the plasma cutter. 2. Direct interference radiated from the plasma cutting leads. 3. Direct interference radiated from feedback into the power lines. 4. Interference from re-radiation of “pickup” by ungrounded metallic objects. Keeping these contributing factors in mind, installing equipment per the following instructions should minimize problems.
Be sure the voltage, phase, and frequency of the input power is as specified on the rating plate, located on the backboard of the machine. Ø CONNECTION PROCEDURE The Inverter LTP8000 must be connected to AC220V±10%, 230V±10%, 240V±10%, 50/60Hz Single phase supply. Plug Wire Connection Example: 220/240V, 50A INPUT (Figure A.0)
The consumables set of electrode, nozzle and cup should install in order as shown in Figure A.2. The LTP8000 can only use genuine LOTOS brand consumables sets of BCON serial. One set of consumables has already been installed in the torch head.

❖ CUT FROM THE EDGE 1 . Hold the torch 90° to the edge of the work piece. . 2 Press the trigger of the torch to start the pilot arc. Hold the torch at the edge (do not continue the cut) until the arc has cut completely through the work piece.
Page 15
❖ PIERCE A WORK PIECE Recommend using 2T function while piercing 1. Hold the torch at an approximate 30° to the work piece, the distance between the torch tip and the work piece should be within 1/16 inch (1.5 mm). 2 .
1) Connect up the air compressor using air filter and regulator as Installation indicates. 2) Have LTP8000 plasma cutting torch and ground cable & clamp ready as Installation indicates, turn the power 3) Adjust the air pressure and make it is adequate to machine, open the valve of pressed air.
