5-3. Typical Configurations When Connected To Constant Voltage (CV) Power Sources
CO2 = Carbon Dioxide
C25 = Argon + 25% Carbon Dioxide
Tri–Mix = 90% 7.5% Argon + 2.5% Carbon Dioxide
No control cable connection exists between the wirefeeder and the CV power
source so the power source contactor circuit must be completed locally.
Consult the wire manufacturer or supplier for recommended shielding gases.

Make sure the contact tips, liners, feedrolls, etc. are selected to match the wire being
used. Set the voltage on the welding power source and the wire feed speed per the
wire, diameter, gas, thickness, joint configurations, and other parameters required.
For best performance, connect weld cables so polarity (DCEN or DCEP) matches that
required by welding wire.
