Reason I'm asking,is, that the Miller catolog 2007 says you can use their 8vs suitcase wire feeder with cc/or/cv.Does anyone know if this works and if so how good is it? Also,Does anyone know what the actual differance is between acytelene hose's and hose's designed for propane? I use my acyt. hose with propane and havent had a problem,but am curious what the big deal is?What exactly IS the physical differance between the specified hoses?????Gary.
I am interested to hear about the CC/MIG combination too. I am told that a voltage sensing feeder will only allow spray transfer with a CC welder. Rubber grade "R" & "RM" acytelene hose isn't rated for propane due to the rubber not holding up to petrolium products, but some people use it anyway. Grade "T" hose is a neoprene that does hold up to petrolium, and is rated for all fuel gasses.
Thanks for the info Dave.
The 8VS feeder is a great unit, but you will have a limited short circuit current. The CV wire feeders maintain a stable consistent voltage, regardless of your amperage output.
Just a last thought.
Constant Current power GMAW does not carry prequalified status with D1.1 work. If your doing code work, all your CC Mig procedures will need to be qualified by testing Per section4.
If the machine has only a CC output, the voltage window the wirefeeder can provide a good short circuit weld is so small. Reason, on a CC machine the main amperage control limits the amount of amperage. IF 125-150 amps is set, the machine will provide only the 125/150 amps and 0.035" steel wire needs about 350 amps to clear the short circuit. Spray transfer is easily attainable when using 80-90% argon w/CO2 remainder. Not easily attainable with 75% argon/25% CO2. And, with CC weld output the wire feeder's wire feed speed determines the voltage.
Cool.Thanks for the info.So it's possible,just not very desierable.I was just wondering.I will hopfully be getting a larger machine by the end of 2007 with CC/CV.Maybe a Lincoln GXT or Bobcat 250.Thanks again,Gary.
If you want a three phase arc; go with the Miller Trailblazer either 302 or 275.
I would second that as well. If you are going to be doing any kind of code work or professional work youre really going to need a stronger machine prefferably with 3 phase arc output. Its night and day compared to the single phase arc machines.
I have considered the trailblazer.Maybe I will go there???I dont see myself needing more than 250 amps/100%,but 3-phase would be cool!!
