Plasma Cutter Function Important Information and Warnings:
NOTICE! The Plasma cutting function of this machine is designed to be a support function and is not designed to be the pri-
mary function of this machine. The Plasma duty cycle of this machine is lower than that of a stand alone Plasma cutter (35%
@ max. ouput). However, when used in normal day to day
“
cut and then weld
”
support activities such as those found com-
monly in portable repair or prototyping/light fabrication situations, the plasma will deliver satisfactory, long
-
lived performance.
Damaged caused by failure to observe the following warnings will not be covered under warranty.
DANGER! Never touch any of the bare portions of the torch power connectors, pilot arc wire, or torch control while the unit is
switched on. Severe injury or death may occur if the torch trigger is accidentally activated or becomes damaged.
WARNING! Never plasma gouge or scarf with this unit. Even though the plasma torch may support gouging consumables,
this unit is not designed for gouging. The long arc behavior associated with gouging and the high voltage spikes caused will
damage this unit.
WARNING! Never use this unit in conjunction with CNC Plasma tables or systems. This unit is designed for use with hand
cutting only. Use with a CNC system will exceed the duty cycle and capability of this machine.
WARNING! Do not try to use (trigger) the Plasma torch while in TIG or Stick modes. For best practice, select the CUT mode,
then turn the machine off before attempting to install the Plasma torch. Triggering the plasma torch while in TIG or Stick
modes may damage the machine.
WARNING! Do not use sun glasses or non cutting glasses to protect the eyes. Use at least a shade 8 for plasma cutting
where the arc is clearly visible. Never use less than a shade 5. Do not use cutting shades rated only for Infrared use, such as
those designed for Oxy
-
Fuel use. These usually do not offer sufficient UV protection unless stated otherwise.
CAUTION! Keep the torch switch isolated and the consumables in place on the torch while the unit is switched on. Turn the
unit off to change consumables. Do not remove the trigger safety guard or attempt to defeat its operation in any manner. If
the trigger safety becomes damaged, replace immediately. Turn the machine off to replace the consumables.
CAUTION! For most cutting applications, use the 2T setting. Do not use 4T unless you are familiar with 4T operation. At-
tempting to use this setting without being thoroughly familiar with this setting may cause a panic stop and can result in severe
burns and injury. 4T is for only experienced users that intend to make long cuts. If you use 4T, remember that the arc will
stay on until the trigger is cycled again. 2T is the simplest operation with a
“
press and hold
”
operation. 4T requires a
“
pull
and release
”
to start the arc. The arc will continue without the trigger being held. The cut will continue until the trigger is
pulled and released once again.
Component Identification and Explanation
NOTICE:
The design of the blow back start
may
cause a slight delay in the arc as the air pressure must built inside the torch tubing and
head to create the pressure needed to force the electrode off the nozzle seat. This may take up to a second, especially when
using longer torches or marginal air supply systems. Restarting the arc in tip saver mode requires retriggering the torch. If
the torch does not light after 3 seconds, let go of the trigger and press it again. If the start or arc is erratic check nozzle and
electrode for tightness and wear.
STOP!
Do not change the process to TIG or Stick while the plasma cutter is connected. This can instantly damage the unit. Remove
the plasma torch before changing to the TIG or Stick process. The Blow
-
back torch design creates a dead short in the torch if
the machine is switched to Stick or TIG while connected. Not only can it damage the torch, it can damage the machine as well.
