Safety Precautions
WARNING: Before performing any installation or operating
procedures read and follow the safety precautions listed below.
Failure to observe these safety precautions can result in
personal injury or death.
Personal Protection: Skin and eye burns resulting from body
exposure to the electric-arc welding rays or hot metal can be
more severe than sunburn:
a. Use a proper face shield fitted with correct filter and cover
plates to protect your eyes, face, neck and ears from sparks
and rays of the cutting arc when cutting or observing cutting.
WARN bystanders not to watch the arc or expose themselves
to the welding-arc rays or hot metal.
b. Wear flameproof gauntlet-type gloves, heavy long-sleeve
shirt, cuffless trousers, high topped shoes and a welding
helmet or cap for hair protection to protect the skin from arc
rays and hot sparks or metal. A flameproof apron may also
be desirable as protection against radiated heat and sparks.
c. Hot sparks or metal can lodge in rolled up sleeves, trouser
cuffs or pockets. Sleeves and collars should be buttoned, and
pockets eliminated from the front of the clothing. Protect
other nearby personnel from arc rays and sparks with a
suitable non-flammable partition.
d. Always wear safety glasses or goggles within the cutting
area. Use safety glasses with side shields or goggles when
chipping slag or grinding. Chipped slag is hot and can travel
considerable distances. Bystanders should also wear safety
glasses or goggles.
Fire Protection: Hot slag, or sparks, can cause serious fires
when in contact with combustible solids, liquids or gases:
a. Remove all combustible materials well away from the
welding area or completely cover the materials with a non-
flammable covering. Such combustible materials include
wood, clothing, sawdust, gasoline, kerosene, paints, solvents,
natural gas, acetylene, propane and similar combustible
articles.

Equipment Maintenance: Faulty or improperly maintained
plasma cutting equipment results in poor cut-quality. It can
cause physical injury or death through fires or electrical shock.
a. Whenever possible, have a qualified person perform the
installation, troubleshooting and maintenance work on the
plasma cutter. Do not perform any electrical work on the
plasma cutter unless qualified to perform such work. Before
performing any maintenance work inside the plasma cutter,
disconnect the machine from the main electrical power
source.
b. Maintain plasma cutting cables, grounding wire and
connections, power cord and plasma cutter in safe working
order. Do not operate the plasma cutter or accessory
equipment in faulty condition. Keep the equipment away
from heat sources such as furnaces, wet conditions such as
water puddles, oil or grease, corrosive atmospheres and
inclement weather.
c. Keep all safety devices and cabinet covers in position and in
good repair. Use the plasma cutter for its intended purpose
and do not modify it in any manner. Unauthorized
maintenance repair will result in loss of warranty coverage.
Additional Safety Information:
a. "Safety in Welding and Cutting" - AWS Z49.1
b. "Recommended Safe Practices for Gas-Shielded Arc
Welding" - AWS A6.1
c. "Safe Practices for Welding and Cutting Containers that Have
Held Combustibles" - AWS A6.0
d. "Recommended Safe Practices for Plasma Arc Cutting" -
AWS A6.3
e. "Recommended Safe Practices for Plasma Arc Welding" -
AWS C5.1
b. Hot sparks or hot metals can fall into cracks in floors or wall
openings and cause a hidden smoldering fire. Make certain
that such openings are protected from hot sparks and metal.
Do not weld, cut or perform other work on used barrels,
drums, tanks or other containers until they have been
completely cleaned.
c. For fire protection, have fire-extinguishing equipment handy
for instant use. After completion of cutting, inspect the work
area for hazardous hot sparks or metal.
Electrical Shock: Voltages in excess of 110V can cause severe
burns or fatal shock. Severity of electrical shock is determined
by the path and amount of current through the body:
a. Never allow live metal parts to touch bare skin or wet
clothing. When standing on metal or welding in a damp area
you must be well insulated. Wear dry gloves and rubber-
soled shoes. Stand on a dry board or platform.
b. Always ground the plasma cutter by connecting a ground
wire between the machine and electrical ground. Do not use
worn, damaged or overloaded welding cables. Use well
maintained equipment.
c. When not cutting, turn off the equipment. Accidental
grounding can cause overheating and create a fire hazard.
Do not coil or loop the welding cable around parts of your
body. Be sure the ground cable is connected to the
workpiece as close to the cutting area as possible. Grounds
connected to the building framework or remote locations
increase the possibility of stray cutting currents.
d. Keep everything dry; clothing, work area, welding cables,
electrode holder, and cutting machine. Fix water leaks
immediately.
Ventilation: Cutting fumes, particularly in confined places,
can cause discomfort and physical harm if breathed over an
extended period of time:
a. Provide adequate ventilation by natural or mechanical
means. Do not cut on galvanized zinc, lead, beryllium, or
cadmium materials unless positive mechanical ventilation is
provided!
b. Do not cut in locations close to chlorinated hydrocarbon
vapors from degreasing or spraying operations. Heat or arc
rays react with solvent vapors forming phosgene, a highly
toxic gas.
c. If you develop momentary eye, nose or throat irritation
during cutting, ventilation is not adequate. Stop work and
take necessary steps to improve ventilation. Discontinue
cutting if physical discomfort persists.
d. Refer to AWS Standard Z49.1 in Item 6 for specific
ventilation recommendations.

Inspection
After removing your plasma cutter from its shipping carton,
inspect the plasma cutter for any concealed damage not seen
upon receiving the unit. Any claims for loss or damage
occurring during shipping must be filed by the purchaser with
the freight company.
Check the inlet air supply at the rear of the cabinet to be sure no
packing materials have gotten inside to obstruct the airflow to
the plasma torch.
Install the carrying strap according to Figure 1.
Plasma/Cooling Gas Connection
Your Micro Cut 380 has been designed to use clean, dry
compressed air as both the plasma and cooling gas. Water
and/or oil in the air will significantly reduce the life of the
electrode and the cutting nozzle, at the same time reducing the
quality of the cut.
Install the bracket with 2 Phillips head screws to the back of
your Micro Cut 380 as shown in Fig 2. Install the regulator in
the quick connect fitting and secure it to the bracket. Install a _
male quick disconnect fitting to match your air supply. Using
the airflow switch (Fig 4, #8), adjust the regulator so the gauge
on the front of the machine reads 65 psi with the air flowing.
4
Safety sensing circuitry has been installed to eliminate arc-
initiation if the pressure and volume are inadequate. If the air
pressure is too low, both the red general alarm led (Fig 3, #7)
and the yellow low air pressure led (Fig 3 #6) will light up.
Damage to your plasma cutter due to excessive water and/or oil
in the air supply line is not covered under warranty. Your Micro
Cut 380 comes equipped with a regulator/filter. In addition,
HTP has 2 filters available for removing any impurities from
the air. If you already have a drier on your compressor, we
recommend the HTP Super Dry (Part # 25300) which is a
disposable in-line filter. This filter uses a desiccant to
completely remove all moisture from the air. The desiccant
is blue when new and turns clear when the filter needs to
be discarded.
Plasma/Cooling Gas Pressure Volume
60 to 75 psi 3 1/2 CFM
If you do not have a drier on your compressor, we strongly
recommend the HTP Max Dry (Part # 25310). This is a 3-stage
filter, which completely removes all oil and water from the air.
The first stage of the Max Dry removes the water which is
present in the air. The second stage of the filter removes any oil
which may be in the air along with particulate down to .03
microns. The final stage is the desiccant drier, which removes
the humidity from the air. The desiccant in the final stage is
reusable. It is blue when it is fresh, and changes to pink when it
has absorbed moisture. Just put the pink desiccant in the oven
to bake the moisture out and reuse. This filter extends the life
of your air tools and is great for painting also.
WARNING: Check the air regulator set every day for proper
pressure, volume and water/oil levels.

(Fig 2) Installing Pressure Regulator

Ground Cable Connection
Assemble the ground cable as shown in Figure 4. The ground
cable is connected to the front (see Fig 4, #10) of the machine.
Plug the cable into the receptacle and twist clockwise until tight.
Connect the ground clamp as close to the workpiece as possible.
This will reduce the possibility of current loss through stray
paths. Always connect the clamp to clean, bare metal. Do not
connect the ground clamp to the piece which will be cut off.
Electrical Connection
All electrical connections should be performed by a qualified
electrician in accordance with the National Electrical Code and
local codes and ordinances. When connecting your plasma
cutter, the yellow-green wire MUST BE CONNECTED TO
GROUND, OR SERIOUS INJURY OR DEATH MAY RESULT!
ELECTRICAL SHOCK CAN KILL! Do not connect an input
wire to the ground terminal. Do not connect the ground
(yellow-green or green) wire to an input (hot) line terminal.
It is also strongly recommended that a fusible line disconnect
switch be installed in the input power circuit to the plasma
machine. This would provide a safe and easy method to
remove all electrical power from your plasma system whenever
it is necessary to perform internal inspection or servicing.
BEFORE ATTEMPTING TO MAKE ANY PRIMARY POWER
CONNECTIONS TO YOUR PLASMA CUTTER, BE SURE
THAT ALL POWER IS OFF BY OPENING THE LINE
DISCONNECT SWITCH.
Your Micro Cut 380 has been designed to operate from 220 volt
single phase power wired for a minimum of 16 amps. The
green or yellow-green wire must be connected to ground. The
blue and brown wires must be connected to the hot legs of the
220-volt power.

1) ON-OFF SWITCH – the On-Off switch is located on the
rear of your Micro Cut 380. I is on and O is off. When the
switch is in the on position, it will light up.
2) CUTTING POWER ADJUSTMENT – the cutting power
adjustment controls the cutting amperage of your Micro Cut
380. It is infinitely variable from 15 to 30 amps. At the lower
power settings, the machine will throw fewer sparks - but will
also cut slower. The maximum cutting power will give you the
maximum cutting speed through all materials.
3) AIR PRESSURE REGULATOR – use the air pressure
regulator to adjust the pressure gauge on the front of the cutter
to 65 psi. The pressure regulator also has a filter, which should
be drained regularly.
4) AIR PRESSURE GUAGE – the air pressure gauge measures
the plasma gas pressure and should be set to 65 psi for optimum
cutting performance. To adjust the plasma gas pressure, flip the
air purge switch (#8) to start air flowing. Adjust the regulator to
achieve the correct pressure while air is flowing through the
plasma torch.
5) YELLOW "CUTTING CURRENT LIGHT – when this
lamp is on, the trigger on the cutting torch is depressed and
either the pilot arc or the cutting arc has been activated. This
lamp will not be illuminated with the trigger depressed when:
A) The cutting arc has been interrupted because the torch was
moved too far away from the workpiece.
B) If the cutting arc is not brought in contact with the
workpiece within 2 seconds.
C) If the electrode or cutting tip is worn out.
6) RED "GENERAL ALARM" LIGHT – this lamp will
illuminate red when the duty cycle of the machine has been
exceeded (30% @ 30 amps). This lamp also indicates an
overvoltage or undervoltage condition. Reset is automatic.
The lamp will also illuminate when the air pressure is too low.
Reset is also automatic.
7) YELLOW "AIR PRESSURE" LIGHT – your Micro Cut
380 has a safety sensing circuit which has been installed to
eliminate the arc ignition if the air pressure and volume are
inadequate. If this occurs, the yellow air pressure light will be
illuminated. Once air pressure has been restored, the light will
go out. Your Micro Cut 380 requires 65 psi of air when air is
flowing through the torch.
8) AIR PURGE SWITCH – the air purge switch allows you
to purge air through the torch, allows you to manually cool the
cutting torch after long periods of cutting, and allows you to set
the air pressure while flowing air through the plasma torch.
To purge the torch, simply flip the toggle switch up and release.
Air will flow for approximately 30 seconds and stop.
9) GREEN "POWER ON" LIGHT – when the machine is
correctly connected to a 220 volt input power supply, and the
on-off switch at the rear of the plasma cutter is turned on, a
green light will be illuminated, indicating your Micro Cut 380
is connected to the correct power supply.
10) GROUND CABLE CONNECTION – this is where
the ground cable connects to the front of your Micro Cut 380.
Align the tab on the ground clamp with the notch in the
connection. Insert the ground clamp and twist to lock in place.
Be sure to connect the ground to the workpiece properly.
(See page 6 – ground cable connection)

(Fig. 5)
Operation
1. Be sure your Micro Cut 380 is connected to a clean, dry
source of com-pressed air with a line pressure of at least 80
but not more than 140 psi. Be sure the air pressure is
adjusted to 65 psi (see Micro Cut 380 Controls #4)
2. Connect your Micro Cut 380 to a 220-volt power supply.
(See electrical connection). Turn the On-Off switch on the
back of the unit on. The green "power on" light will turn on.
The fan will begin to run.
3. Set your cutting power adjustment to the desired amperage.
(usually 30 amps)
4. Refer to the safety suggestions to be sure the operator has
the correct eye protection, gloves, clothing, and that all of the
safety precautions have been followed.

5. Connect the ground clamp to a clean surface on the vehicle
or the work piece that is as close as possible to the area to be
cut. Make sure the ground clamp comes in contact with
clean, freshly ground, bare metal. If you are working on an
automobile, make sure the ignition is off, and disconnect the
battery. Many auto manufacturers recommend the removal
of on-board computers - if you have any questions, check
with the vehicle manufacturer. Be sure not to connect the
ground clamp to the piece which is being cut off.
6. Place the cutting torch on the edge of the material to be cut.
Depress the trigger on the cutting torch. Pre-air flow will
occur for about 1/2 second. The pilot arc will start
immediately after that and will operate for 2 seconds. If the
pilot arc is not brought in contact with the work piece, it will
go out and post air flow will occur for 30 seconds. Once the
main arc is established, keep the plasma torch in contact with
the workpiece. Adjust the cutting speed based on the
thickness and type of material you are cutting. Hold the
plasma torch perpendicular to the work. Move the plasma
torch at a speed which keeps the plasma arc bent anywhere
from 5 to 15 degrees. (See Fig 5). When you release the
trigger, the arc will stop, but air will continue to flow for
about 30 seconds to cool the plasma torch
The highest cutting efficiency is achieved by keeping the
plasma cutting tip perpendicular and in contact with the work
surface putting very little downforce on the plasma torch. If
you move too fast, sparks will shoot up and you will not cut
all the way through the work. If you are cutting correctly all
the plasma sparks will go beneath the panel you are cutting.
7. When piercing a thicker sheet of steel (1/8" thick to 5/16"),
hold the torch at approximately a 45 degree angle and
gradually roll the torch until it is perpendicular to the work
piece (Fig. 6) If the torch is held perpendicular to the work
to start, there will be no where for the slag to flow, and it will
come straight up and damage the gas diffuser, cutting tip, and
electrode.
8. Familiarize yourself with the consumable parts and their
correct assembly onto the torch head (see page 10).
WARNING: Never disassemble the cutting torch unless the
machine has been disconnected from its power supply.
7
Maintenance and Service
Always disconnect the machine from the main power source
before performing any maintenance or service work.
1. Remove machine housing frequently and blow residual
material from inside of machine.
2. Check nozzle and electrode often for excessive wear due to
cutting. The electrode will develop a pit in the center of it.
When the pit reaches approximately 5/64" deep, the electrode
should be replaced. (Fig. 7)
Likewise, when the hole in the center of the cutting tip
becomes enlarged to approximately 1/16" in diameter, the
cutting efficiency will be reduced and the cutting tip should
be replaced.
3. Clean exposed torch consumables often. This will maintain
their life.
4. Check nozzle and electrode often for proper installation.
5. Frequently check the air supply quality. This is the single
most important factor in the maintenance of the plasma
system.
6. If any damage to the machine or torch is noticed, contact
your local distributor or HTP America, Inc. directly at
1-800-USA-WELD.
IF ANY SERVICE OTHER THAN THE AFOREMENTIONED
IS NECESSARY, IT SHOULD BE PERFORMED BY
AUTHORIZED PERSONNEL ONLY.

Cutting Tips
1. When making long, straight cuts, it may be easier to use a
metal straight edge as a guide. Simply clamp it to the
workpiece to be cut. HTP America, Inc. also manufactures a
complete Circle-Cutting and Straight-Line Traversing
Assembly for frequent cutting of circles and lines.
2. When cutting heavier gauge material (up to the machine
capability) it is recommended to initiate the pilot arc off the
edge of the material and dragging the pilot arc to the
workpiece.
3. When making rust repairs, it is possible to place the new
metal over the rusted area and then cut your patch panel at
the same time you cut the rust. This process works similarly
when splicing a quarter panel.
4. Please note that sparks from cutting arcs can damage painted
surfaces. The sparks will also pit glass. We recommend the
use of a welding blanket to protect these surfaces.
5. The best cutting speed is achieved when the plasma arc
penetrates the workpiece at an angle of 5-15 degrees. The
cutting speed is dependent on material thickness and
composition as well as operator proficiency.
6. Never turn the machine off immediately after cutting.
Always allow the post airflow circuitry to run its complete
cycle to ensure proper cooling of the torch head.
7. It is highly recommended that piercing requirements be kept
to a maximum of 75% of rated cutting thickness. This will
greatly enhance the plasma torch's consumable life. When
piercing thick pieces of metal, it is best to hold the cutting
torch at a 45-degree angle to the work until the plasma arc
has pierced the material. Holding the torch perpendicular to
the work will result in sparks and slag firing back up into the
plasma torch, greatly reducing consumable life.
