INTRODUCTION
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
• PORTABLE - Weighing just 44 lbs., (20 kg) it is
easily moved from location to location.
• POWERFUL CUTTING PERFORMANCE -
Genuine cutting capacity is 3/8” (10mm) and
1/2” (12mm) for maximum cut.
• 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 SL60™
1Torch™ provides state of the art technology and
performance of more expensive torches.
