Operating Instructions and Parts Manual
Setup and Components (Continued)
The plasma cutter will perform best when connected directly
◆
to a 120 volt receptacle. Extension cords will have a voltage
drop through the cord and the plug connections. A voltage
drop will reduce the plasma cutter's performance. Extension
cord recommendation is 50 foot [15.24 m] maximum length
with a 14 AWG minimum cord.
NOTE: Many buildings and homes are equipped with 15 and
20 Amp Branch Circuits. The recommended circuit for
operating this Plasma Cutter is a dedicated 20 Amp Branch
Circuit. Check the wall receptacle for a 20 Amp receptacle like
the one shown in Figure 2 and check the circuit box to verify
the receptacle is on a 20 Amp breaker. It is important that
no other electrical devices are concurrently powered by the
same Branch Circuit. Operating this unit on a 15 Amp branch
circuit may result in a tripped breaker.
Connect an air supply to the male quick connect fitting at
◆
the rear of the plasma cutter. Make sure the compressor can
deliver a (recommended) minimum air supply of 1.25 CFM
[35 L/min] @ 40 psi [276 kPa].
Set air pressure with the regulator at the front of the unit to
◆
35 psi [241 kPa]. This is the recommended starting pressure
and it can be adjusted up and down depending upon metal
thickness and cutting performance.
NOTE: This plasma cutter has a Duty Cycle rating of 60%.
◆
Duty Cycle ratings for plasma cutters are established by the
amount of time the unit can cut at its rated load within a 10
minute period. Therefore, this unit can be operated for
3-1/2 minutes of 10 minutes and must be allowed to cool
for 6-1/2 minutes. Exceeding this Duty Cycle will overheat
the unit and the temperature light will illuminate and the
unit will stop its output. After the unit cools, generally about
15 minutes, the temperature light will go out and cutting
operation may resume.
Verify the work clamp is properly connected to the workpiece
◆
at a location close to the cutting path. The work clamp must
be connected to bare metal in an area free of rust, paint, or
other non-conductive substances. See Figure 2.
Do not connect the work clamp to the portion of the metal
◆
that will fall from the main workpiece when cut.
The plasma torch is equipped with a trigger safety guard
◆
feature. This safety feature prevents unintentional triggering
of the torch. Triggering of the torch requires the operator to
insert the index finger between trigger safety guard and the
trigger and then pulling the trigger with the index finger. See
Figure 4.
Wear safety glasses with side shields. Wear a face shield or
◆
helmet with a #8 ANSI filter shade over the safety glasses.
Wear welding gloves to protect hands from burns.
◆
Verify the green light is illuminated. Turn power switch to the
◆
on position and verify the fan is running.
IMPORTANT: Do not pull trigger with the torch held away
◆
from the workpiece. Operating the flame in open air will
reduce the life of the tip and electrode. See Figure 5.
