Can I use flux-cored wires (FCAW-GS or FCAW-SS) on a constant current (CC) stick welding power source?

Our flux-cored wires are designed to operate on constant voltage (CV) DC machines. If used on a constant current (CC) machine, any small changes in electrical stickout (length of the wire from the end of the contact tip to workpiece) will produce large voltage fluctuations, resulting in stubbing and porosity. Therefore, using flux-cored wires on CC is not recommended.
