precautions and safe practices must be accomplished.
Failure to observe certain precautions could result in serious
personnel injury or severe equipment damage. The
following precautions are general guidelines applicable when
working with cutting machines. More explicit precautions
pertaining to the basic machine and accessories are found
in the instruction literature. For a wide scope of safety
information on the field of cutting and welding apparatus,
obtain and read the publications listed in the Recommended
References.

Keep hands clear of torch and slide during operation.
WARNING
!
Fume hazard.
Fumes and gases generated by the plasma cutting
process can be hazardous to your health.
· Do NOT breathe fumes.
· Do not operate plasma torch without fume removal
system operating properly.
· Use additional ventilation to remove fumes if
necessary.
· Use approved respirator if ventilation is not
adequate.
WARNING
!
Hot Torch Could Burn Skin
Torch is “wet” with cooling water and water
injection but may still get hot during high ampere
cutting.
Allow torch to cool before servicing.
Never touch torch unless plasma power supply
has been turned off.
SECTION 1 SAFETY
PT-15XL Plasmarc Cutting Torch 1-6
WARNING
!
WARNING
!
Radiation hazard.
Arc rays can injure eyes and burn skin.
· Wear correct eye and body protection.
· Wear dark safety glasses or goggles with side
shields. Refer to following chart for recommended
lens shades for plasma cutting:
Arc Current Lens Shade
Up to 100 Amps Shade No. 8
100-200 Amps Shade No. 10
200-400 Amps Shade No. 12
Over 400 Amps Shade No. 14
· Replace glasses/goggles when lenses are pitted or
broken
· Warn others in area not to look directly at the arc
unless wearing appropriate safety glasses.
· Prepare cutting area to reduce reflection and
transmission of ultraviolet light.
· Paint walls and other surfaces with dark colors to
reduce reflections.
· Install protective screens or curtains to reduce
ultraviolet transmission.
Ruptured Gas Cylinders Can Kill
Mishandling gas cylinders can rupture and violently
release gas.
· Avoid rough handling of cylinders.
· Keep cylinder valves closed when not in use.
· Maintain hoses and fittings in good condition.
· Always secure cylinders in an upright position by
chain or strap to a suitable stable object not part of an
electrical circuit.
· Locate cylinders away from heat, sparks and
flames. Never strike an arc on a cylinder.
· Refer to CGA Standard P-1, “Precautions for Safe
Handling of Compressed Gases in Cylinders”, available
from Compressed Gas Association.
SECTION 1 SAFETY
PT-15XL Plasmarc Cutting Torch 1-7
WARNING
!
Spark hazard.
Heat, spatter, and sparks cause fire and burns.
· Do not cut near combustible material.
· Do not cut containers that have held
combustibles.
· Do not have on your person any combustibles
(e.g. butane lighter).
· Pilot arc can cause burns. Keep torch nozzle
away from yourself and others when activating
plasma process.
· Wear correct eye and body protection.
· Wear gauntlet gloves, safety shoes and hat.
· Wear flame-retardant clothing that covers all
exposed areas.
· Wear cuffless trousers to prevent entry of
sparks and slag.
WARNING
!
Explosion hazard.
Certain molten aluminum-lithium (Al-Li) alloys can
cause explosions when plasma cut with water.
Do not plasma cut the following Al-Li alloys with
water:
Alithlite (Alcoa) X8192 (Alcoa)
Alithally (Alcoa) Navalite (US Navy)
2090 Alloy (Alcoa) Lockalite (Lockheed)
X8090A (Alcoa) Kalite (Kaiser)
X8092 (Alcoa) 8091 (Alcan)
· These alloys should only be dry cut on a dry
table.
· DO NOT dry cut over water.
· Contact your aluminum supplier for additional
safety information regarding hazards associated
with these alloys
.
SECTION 1 SAFETY
PT-15XL Plasmarc Cutting Torch 1-8
DANGER
!
Hydrogen explosion hazard.
· Do not cut under water with Hydrogen gas!
· Hydrogen explosions can cause personal
injury or death.
· Hydrogen can create explosive gas pockets
in the water table. These pockets will explode
when ignited by sparks or the plasma arc.
· Before cutting, be aware of possible
hydrogen sources in the water table – molten
metal reaction, slow chemical reaction and
some plasma gases.
· Explosive gas pockets accumulate
underneath the cutting plate and inside the
water table.
· Clean slag (especially fine particles) from
bottom of table frequently. Refill table with
clean water.
· Do not leave plate on table overnight.
· If water table has not been used for several
hours, vibrate or jolt it to break up hydrogen
pockets before laying plate on the table.
· If possible, change water level between cuts
to break up hydrogen pockets.
· Maintain water pH level near 7 (neutral).
· Programmed part spacing should be a
minimum of twice the kerf width to ensure
material is always under the kerf.
· When cutting above water, use fans to
circulate air between plate and water surface.

1.6 Service Precautions
CAUTION
Establish and adhere to preventive maintenance. A
composite program can be established from
recommended schedules in the instruction literature.
Avoid leaving test equipment or hand tools on
machine. Severe electrical or mechanical damage
could occur to equipment or machine.
CAUTION
!
Extreme caution should be used when probing
circuitry with an oscilloscope or voltmeter. Integrated
circuits are susceptible to over voltage damage.
Power off before using test probes to prevent
accidental shorting of components.
All circuit boards securely seated in sockets, all cables
properly connected, all cabinets closed and locked, all
guards and covers replaced before power is turned
on.
Never plug or unplug a printed circuit board while
machine power is on. Instantaneous surges of voltage
and current can damage electronic components.
WARNING
!
Hot Torch Could Result In Burn Injury
Torch is “wet” with cooling water and water
injection but may still be hot immediately after high
ampere cutting.
Allow torch to cool before servicing.
WARNING
!
Electric Shock Could Kill or Injure
Turn OFF plasma power supply before servicing
torch.

2.1 General
The PT-15XL Mechanized Plasma Cutting Torch is
designed for plasma water injection cutting using
nitrogen, oxygen or H-35. (H-35 is industry
nomenclature for a mixture of 65% argon and 35%
hydrogen. It can effectively cut mild steel, stainless
steel and aluminum in 1/8" to 3" (3,2mm to
76,2mm) material. A high current nozzle is available
for cutting materials from 3" to 6" (76,2mm
152,4mm) thickness at up to 1000 amperes.
Note: Because of slower cutting speeds, dross
formation is to be expected when cutting thicker
materials (3" to 6").
2.2 Scope
The purpose of this manual is to provide the
operator with all the information required to install
and operate the PT-15XL Mechanized Plasma
Cutting Torch. Technical reference material is also
