1. Control Settings and Weld Parameters When Connected to Constant Current (CC) Power Sources

5-3. Typical Configurations When Connected To Constant Voltage (CV) Power Sources

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.

CO 2 = Carbon Dioxide

C25 = Argon + 25% Carbon Dioxide

Tri–Mix = 90% Helium + 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.
