2.01 Overview

Plasma is a gas which has been heated to an extremely
high temperature and ionized so that it becomes elec-
trically conductive. The plasma arc cutting process uses
this plasma to transfer an electrical arc to the work-
piece. The metal to be cut is melted by the heat of the
arc and then blown away.

NOTE:
*Duty Cycle is the percentage of time the sys-
tem can be operated without overheating. Duty
cycle is reduced if primary input voltage (AC) is
low or the DC voltage is higher than shown in
previous chart.

2.03 Features

• RELIABLE AND POWERFUL - This inverter
based power supply operates on standard 230V
single or three phase power.
• POWERFUL CUTTING PERFORMANCE -
Maximum cutting capacity is 1" (25mm).
• CUTS MOST METALS - Useful for most metals
such as stainless steel, aluminum, mild steel, cop-
per and alloys.
• NO HIGH FREQUENCY - Starts without high-
frequency so it won't interfere with controls or
computers.
• MORE TORCH, LESS MONEY - The SL100™
1Torch™ provides state of the art technology and
performance of more expensive torches.
