FLOW METER
The flowmeter shows the flow rate of shielding gas
and has a valve to adjust the flow. The flow meter is
calibrated for CO

/Ar blends. The middle
of the ball indicates the flow rate of shielding gas.
Adjust the flow rate 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.
