To cut the steel sheets of thickness 0,5-1 mm (0.02-0.04 inches), it is sufficient to set MODE I to position 1-4 and set voltage to 190-
210 V. Steel sheets of 1-3 mm (0,04-0,12 inches) may be cut using MODE I and setting the current indicator to position 6 and
setting the voltage display to 210 -230 V.
Thicker sheets should be cut using MODE II. Set the MODE I current indicator to position 6 and voltage to 210-220 V. Then
activate MODE II.
Direct arc of MODE II appears automatically as the torch nozzle is brought 2-3 mm (0.08-0.12 inches) from the surface of the
workpiece.
Select rate of torch translation along cut such that the arc stays on the workpiece material and molten metal is removed. If torch
translation rate is too high, metal will not be cut, and if translation rate is too low or zero, direct arc may break because there is no
metal in the cut.

When cutting, keep in mind that the unit’s plasma jet is supposed to remove molten metal through the cut
This requires cuts to be initiated at the workpiece edge If this should prove impossible from the process standpoint, a hole must be
drilled to be used for cut initiation For thin sheet metal, “punch-through”cutting may be used where the initial hole is obtained by
burning through the metal When using “punch-through”cutting, protect the torch from backwash and sparks until a through hole is
obtained This is accomplished by holding the torch at less than 90 degrees to the workpiece surface at the start of the “punch-
through”procedure Please note, that it is not possible to achieve a high-quality cut using the “punch-through”technique

etal and Non-Metal Cutting Techniques
Plasma jet high temperature and effluence rates support the cutting of practically any non-flammable material, including ferrous and
non-ferrous metals ceramic materials, concrete, stone A cutting rate of 7 mm (0,3 inch) per second can be achieved for low-alloyed
steels with thicknesses of up to 2 mm (0.08 inch), and up to 1 mm (0,04 inch) per second for thicknesses of 10 mm (0,4 inch)
Insulating materials are cut in MODE I.
Example Braze welding of Copper for Electrical Engineering Applications and Aluminum Alloy

Stainless steel tubing is roughened with a coarse file, coated in aluminum flux and treated with aluminum wire filler. This area is
subsequently treated with flux for welding aluminum.Aluminum tubing is then brazed to stainless steel tubing using aluminum wire.

.
,
The device works from the household electric system, using for welding and brazing a
water solution of ethyl alcohol , and for cutting just water. The device can work
on any water, and quality of welding and cutting do not depend on quality of water.
However, to increase service life and simplification of maintenance service, it is better
to use water with small amount of minerals, the best is distilled water.

Copper and Copper-Base Metal Welding and Braze welding Technology
Copper fillers, copper-zinc fillers, copper-phosphorous fillers, and specialized fluxes are used in the course of welding and braze
welding
It is best to use simple water rather than a water/alcohol mixture and preliminary heating of workpiece for braze welding of copper.

ast Iron Welding Technology
Cast iron welding for thicknesses up to 3 mm (0,12 inch) is performed in MODE II wire and pig iron are used as fillers
Preheating is required before cast iron welding. Do not remove torch immediately after weld is finished but raise it gradually rocking it
slowly back and forth along weldment
