Hello Lawrence, I figured you would already have a half a dozen of these(kidding). I first had an opportunity to work with this system at a Miller "Weld Camp" about a year ago. They allowed an instructor and two students each to spend 2 days at their district training facility. My partner and I both brought 2 students to participate. Got to "hot rod" this system and a lot of their other ones while we were there. I was definitely impressed with it's capabilities. Recently one of our shops in town purchased a system, only with the single feeder. They have used it mainly on aluminum projects and some on stainless ones. Really good results. Will try to include updates as we get into using it. Best regards, Allan
Hello Lawrence, our Miller rep. showed up today and gave a bunch of our students the low-down on many of the basic capabilities of the 352 MPa system. Then after giving the discussion and demonstration end of it he let them have at it, mainly with the aluminum side of the feeding system.
Explained the term "synergic" and showed them how it worked in action. Also showed them how the "crater fill" feature worked and explained why it is "suggested" to be used. Spoke of the "start" function and how it allowed for avoidance of cold stacking and LOF when doing a restart or even starting a new bead.
Yesterday my partner, I, and our assistant instructor had a chance to play around with it a bit. We were able to run an aluminum bead vertical up on the edge of an 1/8" piece of material with 3/64" 5356 wire and it actually stacked rather nicely. Among a number of other scenarios, by simply adjusting the wire speed, we were able to achieve some very acceptable visual and mechanical results. Today while I was "researching", oh I guess I should be honest "playing around", I was able to run an outside corner joint on 16 GA. SS vertical up with .045 316 LSI solid wire. Set the arc length to 50, the wire speed to 50, and the profile pulse frequency to 2.5 and pointed it slightly uphill and pushed it along steadily and smoothly resulting in a nice outside fill and just a slight burn-through on the back side. Gonna have a lot of "research and developement time on this one", Okay, "playtime".
I will see about getting some photographs of some of the beads and giving the parameters and listing which features were being used or not and how they were set up concerning the specific parameters. Even though Miller has simplified much of the adjustments of this system there is still plenty that a person could explore about it and how to apply it in everyday use. Best regards, Allan
