SHIELDING GAS CONNECTION
CYLINDER may explode if
damaged.
• Keep cylinder upright and
chained to support.
• Keep cylinder away from areas where it may be
damaged.
• Never lift welder with cylinder attached.
• Never allow welding electrode to touch cylinder.
• Keep cylinder away from welding or other live
electrical circuits.
• BUILD UP OF SHIELDING GAS MAY
HARM HEALTH OR KILL.
• Shut off shielding gas supply when not
in use.
• See American National Standard Z-49.1, "Safety
in Welding and Cutting” Published by the
American Welding Society.
------------------------------------------------------------------------
Maximum inlet pressure is 100 psi. (6.9 bar.)
Install the shielding gas supply as follows:
1. Secure the cylinder to prevent it from falling.
2. Remove the cylinder cap. Inspect the cylinder valves
and regulator for damaged threads, dirt, dust, oil or
grease. Remove dust and dirt with a clean cloth. DO
NOT ATTACH THE REGULATOR IF OIL, GREASE
OR DAMAGE IS PRESENT! Inform your gas supplier
of this condition. Oil or grease in the presence of high
pressure oxygen is explosive.
3. Stand to one side away from the outlet and open the
cylinder valve for an instant. This blows away any dust
or dirt which may have accumulated in the valve out-
let.
4. Attach the flow regulator to the cylinder valve and
tighten the union nut(s) securely with a wrench. Note:
if connecting to 100% CO2 cylinder, insert regulator
adapter between regulator and cylinder valve. If
adapter is equipped with a plastic washer, be sure it is
seated for connection to the CO2 cylinder.
5. Attach one end of the inlet hose to the outlet fitting of
the flow regulator. Attach the other end to the welding
system shielding gas inlet. Tighten the union nuts with
a wrench.
6. Before opening the cylinder valve, turn the regulator
adjusting knob counterclockwise until the adjusting
spring pressure is released.
7. Standing to one side, open the cylinder valve slowly a
fraction of a turn. When the cylinder pressure gage
stops moving, open the valve fully.
8. The flow regulator is adjustable. Adjust it to the flow
rate recommended for the procedure and process
being used before making a weld.

TRIGGER CONNECTIONS
There is one circular connector for the gun trigger on the
front of the RED-D-ARC LN25™ PRO EXTREME DUAL
POWER.
Note – if the gun trigger is already depressed when the
feeder is powered up, the feeder will not activate.
Release and then press the gun trigger to begin welding.
The 83% wire feed speed reduces the wire feed speed to
83% of the original set value when activated. For exam-
ple, if the original wfs = 200 in/min, the feeder will regu-
late to 0.83 x 200 = 166 in/min.
The 83% trigger requires a gun with a dual procedure
switch.
This feature is often useful when welding pipe, and a
“cooler” procedure is required on the bottom portion.
CONTROL CABLE CONNECTOR
The control cable connector is present only on the
Dual Power Feeders.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts.
• Welding Voltage is present on pins H,
I, K and N when Dual Power feeders
are operating as Accross the Arc
feeder.
