I was wondering if it's possible to wire weld CC instead of CV with my Bobcat 225? If I switch to stick mode and switch my feeder to CC would this work without damaging my feeder, and would there be any advantage to doing so.Thanks
Reply:Don (dda52) prefers CC with his VOLTAGE-sensing feeder on his old Bobcat.
Reply:He prefers it because he has figured out that the CV output on his Bobus is busted. If I don't use CC, I don't weld.I have noticed that FCAW with CC will give you a little tighter control on the voltage, not much, but a little. You will also be able to go a little lower since the Bobus CV starts at 17vdc and the feeders can go down to 14-15vdc. Using a CC/CV feeder on CC with the switch in the CC position will be fine since that is what it was made for. Now wire selection can be a problem. Some wires do not like to run on CC. Just check the specs, it will be in there. I am running mostly Linc and Hobart wire and not having any issues. Not even with the dual shield. They all run fine....when my Bobus is welding fine. The CC current will be a bit rougher, but not extremely. I like the CV a lot better, I just can't run it. The Bobus in my case is being replaced soon, so I will be in the CV welding mode once again.
Reply:I have used cc mode with a different cc power source. It works fine with higher amps and thicker material for me. In fact, that's why I got a cc/cv feeder to begin with...to use on a cc powersource. It takes a bit more adjusting, but once it's humming, away you go. It works really well when spraying.Smithboy...if it ain't broke, you ain't tryin'. |
