1.1 Introduction

The process of cutting metals with plasma equipment

provides industry with a valuable and versatile tool. ESAB

cutting machines are designed to provide both operation

safety and efficiency. However, as with any machine tool,

sensible attention to operating procedures, precautions, and

safe practices is necessary to achieve a full measure of

usefulness. Whether an individual is involved with operation,

servicing, or as an observer, compliance with established

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.

1.2 Safety Notations And Symbols

The following words and symbols are used throughout this

manual. They indicate different levels of required safety

involvement.

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.

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

provided to assist in troubleshooting the cutting

package.
