So whats the Down Side

admin

Whats the down side to the CC models vs the CC/CV.  primary use for me will be mig with a heavy duty cylce but want the tig options for stainless and mild steel.
Reply:You can't Mig with CC.  CC for Tig, CV for Mig.
Reply:well that most definately answers my question thanks for saving my butt
Reply:I assume you're asking about an XMT or a Big Blue or Big 40 or some other machine that has models available in both CC-only and CC/CV?  The CC/CV machines are true multi-process machines.  You can mig/flux, tig and stick weld from them, as well as air-arc.  The CC-only machines are made for stick, tig and air-arc.Although it is possible to wire weld (mig and fluxcore) with constant current, constant-voltage is the best choice for wire welding.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:Well, you learn something new everyday.  The Lincoln LN-25 wire feeder has an internal switch that allows you to select CC or CV, so you can hook it up to a CC power source.  It evidently monitors the arc-voltage and modulates the wire-feed motor speed to maintain a constant voltage for wire welding with a CC power source.

Reply:Thanks for the info.  SundownIII just post a similar thing on this thread:http://weldingweb.com/vbb/showthread.php?t=43031Good to know about the limitations.
