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 CO2, Ar, and CO2/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.
