HTP MicroCut 45 DV

OPERATOR’S MANUAL

General Information

Thank you and congratulations on purchasing an HTP MicroCut 45DV. With many

welding and cutting equipment options available on the market today, we appreciate your

purchase, as well as the confidence you put into HTP through purchasing one of our

products.

The versatile MicroCut 45DV works as a manual cutter and/or with a CNC plasma cutting

table. The HTP MicroCut 45DV has a dedicated CNC mode. In order to use this as a CNC

cutter you will need to purchase the CNC torch. You can also operate the MicroCut 45 DV

manually with a 20’ hand torch. If you purchased the 20’ hand torch, you can always

upgrade your machine to meet CNC plasma cutting table compatibility at a later date. As

an added bonus, the hand torch and machine torch utilize the same consumables, apart

from the shield cap, so you only need to keep on-hand a single style of replacement parts.

We hope you enjoy working with your new plasma cutting machine! If, at any time, you

need help setting up or operating your plasma cutter, at any time, please feel free to contact

us: 847-357-0700

1.Safety

Important Safety Precautions

OPERATION AND MAINTENANCE OF PLASMA EQUIPMENT CAN BE DANGEROUS

AND HAZARDOUS TO YOUR HEALTH.

Plasma cutting produces intense electric and magnetic emissions that may interfere with the proper

function of cardiac pacemakers, hearing aids, or other electronic health equipment. Persons who work

near plasma cutting applications should consult their medical health professional and the manufacturer

of the health equipment to determine whether a hazard exists. To prevent possible injury;read,

understand, and follow all warnings, safety precautions and instructions before using the equipment.

GASES AND FUMES

Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your

health.

• Keep all fumes and gases from the breathing area. Keep your head out of the cutting fume plume.

• Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.

• The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings

on the metal, and the different processes. You must be very careful when cutting any metals which may

contain one or more of the following:

Antimo

Chromiu

Mercury

Berylliu

Arsenic

Cobalt

Nickel

Lead

Barium

Copper

Seleniu

Silver

Cadmiu

Manganes

Vanadiu

Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are

using. These MSDSs will give you the information regarding the kind and amount of fumes and gases

that may be dangerous to your health.

• Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.

• Do not use the plasma torch in an area where combustible/explosive gases or materials are located.

• Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove all

sources of these vapors.

ELECTRIC SHOCK

Electric Shock can injure or kill. The plasma process uses and produces high voltage electrical energy.

This electric energy can cause severe or fatal shock to the operator or others in the workplace.

• Never touch any parts that are electrically “live” or “hot.”

• Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the cutting

circuit.

• Repair or replace all worn or damaged parts.

• Extra care must be taken when the workplace is moist or damp.

• Disconnect power source before performing any service or repairs.

• Read and follow all the instructions in the Operating Manual.

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag, sparks, or the plasma arc.

• Be sure there is no combustible or flammable material in the workplace. Any material that cannot be

removed must be protected.

• Ventilate all flammable or explosive vapors from the workplace.

• Do not cut or weld on containers that may have held combustibles.

• Provide a fire watch when working in an area where fire hazards may exist.

• Hydrogen gas may be formed and trapped under aluminum workpieces when they are cut underwater

or while using a water table. DO NOT cut aluminum alloys underwater or on a water table unless the

hydrogen gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited will cause an

explosion.

NOISE

Noise can cause permanent hearing loss. Plasma processes can cause noise levels to exceed safe limits.

You must protect your ears from loud noise to prevent permanent loss of hearing.

• To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs. Protect others in

the workplace.

• Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.

PLASMAARC RAYS

Plasma Arc Rays can injure your eyes and burn your skin. The plasma arc process produces very bright

ultra violet and infra-red light. These arc rays will damage your eyes and burn your skin if you are not

properly protected.

• To protect your eyes, always wear a cutting helmet or shield. Also,always wear safety glasses with

side shields, goggles or other protective eye wear.

• Wear cutting gloves and suitable clothing to protect your skin from the arc rays and sparks.

• Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.

• Protect others in the work area from the arc rays. Use protective booths, screens or shields.
