FLOW METER
The flowmeter shows the flow rate of shielding gas
and has a valve to adjust the flow. The flow meter is
scaled for CO
2 , Ar, and CO 2 /Ar blends. It is not cali-
brated and is for reference purposes only. The middle
of the ball indicates the flow rate of shielding gas.
Adjust the flow rate while depressing the GAS
PURGE switch by turning the valve at the bottom of
the meter. Most weld procedures require 25-40 scfh
(11.8 - 18.9 lpm) for sufficient shielding gas coverage.
Gun angle, nozzle diameter, joint configuration and
wind conditions may effect the amount of shielding
gas required.
When using a wire feeder with a flow meter, adjust the
regulator at the shield gas bottle or supply to a flow
rate that is higher than the flow rate indicated on the
feeder flow meter. Note that most regulators are cali-
brated based upon having low restrictions on the out-
let. The valve on the feeder flow meter creates a high
restriction and may cause errors in the readings at the
supply regulator. Set the gas flow rate using the
feeder flow meter reading and not the supply regulator
reading.
Only use a pressure regulator (like K586-1) at the gas
bottle or supply. Do not use a flow regulator.

OPERATION ON LINCNET POWER
SOURCES
The POWER FEED™ 25M is an ArcLink wire feeder
and is designed for operating on ArcLink Power Wave
power sources. It is also capable of operating on older
LincNet Power Wave power sources though not all of
the features will be active.
When operating with a LincNet power source,
• Limits and Lock-outs are not available.
• The weld mode description is not displayed when
choosing weld modes.
• When the weld mode is changed, any Arc Control
values will remain as set for the previous weld
mode.
• Push-Pull guns will not function.
• The IR port will not operate.
• Error codes will by displayed as "ERR100". Error
codes are deciphered by the flashing of the Status
LED.
• In the Set-Up menu, only parameters P.0 to P.99
are available.
