SAFETY
PLEASE READ AND UNDERSTAND THE FOLLOWING SAFETY HIGHLIGHTS.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS. ARC AND TIG WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
vELECTRIC AND MAGNETIC FIELDS may be dangerous
ØElectric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Plasma cutting current creates EMF fields around plasma cutting cables and plasma cutters.
ØEMF fields may interfere with some pacemakers, and users of plasma cutter having pacemakers should consult their physician before operating.
ØExposure to EMF fields in plasma cutting may have other health effects which are now not known.
ØUse the following procedures in order to minimize exposure to EMF fields from the cutting circuit:
Connect the work cable to the work piece as close as possible to the area being cut.
Do not work next to power source.
vELECTRIC SHOCK can be fatal
ØThe electrode and work (or ground) circuits are electrically “hot” when the machine is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
ØInsulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
ØAlways be sure the work cable makes a good electrical connection with the metal being cut. The connection should be as close as possible to the area being cut.
ØGround the work metal to be cut to a good electrical (earth) ground.
ØMaintain the plasma cutting torch, work clamp, power cable and cutting machine in good, safe operating condition. Replace damaged insulation.
ØNever dip the electrode in water for cooling.
ØWhen working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
vARC RAYS can burn
ØUse a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when plasma cutting or observing open arc plasma cutting.
ØUse suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
ØProtect other nearby personnel with suitable, non-flammable screening and/or warn them

not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
vFUMES AND GASES can be dangerous
ØPlasma 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. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when cutting on galvanized steel.
ØDo not cut in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products.
ØRead and understand the manufacturer’s instructions for this equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer’s safety practices. MSDS forms are available from your welding distributor or from the manufacturer.
vCUTTING SPARKS can cause fire or explosion
ØRemove fire hazards from the cutting area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that cutting sparks and hot materials from cutting can easily go through small cracks and openings to adjacent areas. Avoid cutting near hydraulic lines. Have a fire extinguisher readily available.
ØWhere compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations.
ØDo not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been “cleaned”.
ØSparks and spatter are thrown from the cutting arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuff-less trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a plasma cutting area.
ØConnect the work cable to the work as close to the cutting area as practical. Work cables connected to the building framework or other locations away from the cutting area increase the possibility of the cutting current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
vCYLINDER may explode if damaged
ØUse only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
ØAlways keep cylinders in an upright position securely chained to an undercarriage or fixed support.
ØCylinders should be located:
Away from areas where they may be struck or subjected to physical damage.
A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame.
3
ØNever allow any electrically “hot” parts to touch a cylinder.
ØKeep your head and face away from the cylinder valve outlet when opening the cylinder valve.
ØValve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
v ELECTRICALLY POWERED EQUIPMENT can be dangerous
ØTurn off input power using the disconnect switch at the fuse box before working on the equipment.
ØInstall equipment in accordance with the local codes and the manufacturer’s recommendations.
ØGround the equipment in accordance with the manufacturer’s recommendations.
vMOVING PARTS can cause injury
ØKeep away from moving parts such as fans.
ØKeep all doors, panels, covers, and guards closed and securely in place.
Please read this Operation Manual carefully and thoroughly before attempting to operate this machine. Keep this manual handy for quick reference. Pay close attention to the safety instructions provided for your own protection.

SPECIFICATIONS
v 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 incorporate the latest high frequency inverter technology using V-MOSFETs, along with PWM (Pulse Width Modulation), the combination of which help deliver a far more constant, concentrated and precise current to the cutting surface. With this plasma cutter, the user can achieve smooth, clean and uniform cuts on a wide range of surfaces with minimal heat input and without distortion of metal. It is very easy to use by the DIY user, while fully accommodating the demands of professional operators.
ü80-amp pilot arc plasma cutter
üAutomatic dual frequency (50/60Hz)
üHigh frequency start and contact start hand torch
üSuitable for stainless steel, alloy steel, mild steel, copper and aluminum, etc.
