Cut with the Machine Torch
Powermax45 XP Operator Manual 809240 111
Cut stainless steel with F5
You can use F5 gas to cut stainless steel with Duramax Lock torches on the Powermax45 XP. When
used with a Powermax system, F5 is recommended only for cutting stainless steel to achieve to the
advantages in cut quality listed below.
See page 131 for a cut chart on cutting stainless steel with F5.
Plasma cutting with F5 produces smooth, shiny cuts with silver edges that are close to the base
color of the metal. F5 avoids the rough, dark finish that typically results with air plasma cutting.
WARNING
TOXIC FUMES CAN CAUSE INJURY OR DEATH
Some metals, including stainless steel, may release toxic fumes when cut. Make sure
your work site has adequate ventilation to ensure that the air quality level meets all
local and national standards and regulations. Refer to the Safety and Compliance
Manual (80669C) for more information.
F5: Advantages F5: Disadvantages F5: Similarities to air
• Smooth, shiny cut edge
• Silver cut edge, similar to the
base color of the metal – does
not leave the rough, dark
surface that air produces
• No oxidation of the cut
surface – the cut steel
maintains its corrosion
resistance
• Ability to use the same
Duramax Lock consumables as
for standard cutting and
gouging with air (includes
CopperPlus™ electrodes)
• Advantages limited to stainless
steel
•Slower cut speeds
• F5 gas is more expensive than
compressed air
• Not recommended for
thicknesses less than 3 mm or
10 gauge (GA) or for use with
FineCut
®
consumables
• Slightly degraded cut quality on
bevel cuts
• Approximately the same
amount of dross. With F5 and
with air, stainless steel dross is
dark in color and can be
challenging to remove.
• Approximately the same gas
pressure requirements
