SPECIAL WELDING PROCESSES
AVAILABLE ON THIS MACHINE
POWER MODE™
The Power Mode™ process was developed by Lincoln
to maintain a stable and smooth arc at low procedure
settings which are needed to weld thin metal without
pop-outs or burning-through. For Aluminum welding, it
provides excellent control and the ability to maintain
constant arc length. This results in improved welding
performance in two primary types of applications.
• Short Arc MIG at low procedure settings.
• Aluminum MIG welding.
Power Mode™ is a method of high speed regulation of
the output power whenever an arc is established. It
provides a fast response to changes in the arc. The
higher the Power Mode Setting, the longer the arc. If a
welding procedure is not established, the best way to
determine the Power Mode Setting is by experimenta-
tion until the desired output result is established.
In the Power Mode variables need to be set:
• Wire Feed Speed
• Output
• Arc Control
Setting up a Power Mode procedure is similar to set-
ting a CV MIG procedure. Select a shielding gas
appropriate for a short arc process.
• For steel, use 75/25 Ar/CO2 shield gas.
• For Stainless, select a Helium blend Tri-Mix.
• For Aluminum, use 100% Ar.
Start by setting the wire feed speed based upon mate-
rial thickness and appropriate travel speed. Then
adjust the Output knob as follows:
• For steel, listen for the traditional “frying egg”
sound of a good short-arc MIG procedure to know
you have the process set correctly.
• For aluminum, simply adjust the Output knob until
the desired arc length is obtained.

DOES NOT correspond to voltage.
