  • Stand off on miller 375?

    I have a new miller 375 and am lookig for a good way to keep the stand off right. I have the roller stand off and think it is a little big and not really worth the bother. I know thermaldyne (iThink) uses a 4 way cross drag cup and then another one uses a silver/chrome adapter with two guides on it. It is smaller and closer to the tip. Could this be used or is there something better. I have been dragging the tip alot and I know that is killing the consumable cost.
    TIA

    Oh yea this is my first post and I will need help with a new to me mm250

    Correct me if I am wrong but I thought those units have a drag setup built into the nozzle. I also thought can take that part off for a stand off type cutting.
    I have the Thermal type and the roller setup and had the esab two ear setup. I really like the exposed tip with a guide for the correct standoff about the best.

    I take that back, I like this setup better.

    I just cut some 1'' steel tonight, and it cut without a bevel or hardly any I could see. I think Thermal-Dynamics really has really got the SL 100 (one torch) dailed in.

    Ps- that little machine you have is pretty impressive for the 27 amps it puts out.

    I observed the Miller rep cut some .0750 with that machine. That is after I said the Thermal cutmaster 38 could do it.

      dapozer,

      The Miller part number for the standoff roller guide is 194 883. Miller also makes a circle cutting guide for this unit. The part number is 195 981. These numbers are designed to work with the ICE-27C torch. Check your torch model number (on torch handle) and confirm before ordering. If you have a different torch, contact your dealer or Miller tech support at 1-800-4-A MILLER before odering.


      Scott V,

      I believe the ICE-27C torch comes with standard stand-off tip and is not designed to use a drag shield. You can drag the stand-off tip, but material thickness, cut quality, and tip life are signifigantly diminished.

      By the way that's a nice picture. Is it CNC controlled? Here's a Burny 5 CNC with the small O/A torch. It had an older model Thermal plasma torch/power source and was revamped with a Hypertherm G3 less than a year ago.

        Hawk,
        It's a Practical cnc hobby type 5'X 10 table. 5'-5'' X 10'- 5'' cutting ability.
        It not too bad of a machine for the cost and the former tech that worked for them, has some good upgrades in the works. I needed one that came apart to get down into my basement.

        Here is another pic, this is my girlfriend with my esab 1500

            Scott V,

            Nice work. You are lucky. My wife will not even step foot in my shop let alone work the equipment. She is really good at soldering stained glass and would probably do well at welding with some training and practice, but...


            Mike W,

            Most of my aluminum and stainless steel is purchased per job. However, common items like 1", 3/4", 1/2", and 1/4" plate are purchased in quantity and stored. Also common square tube sizes up to 4" is also stock. It can be a confusing process. If the material stock pile not turn before the price drops, then it really hurts. I can get a much better deal on steel in quantity. Therefore, that is the way to go unless prices are volatile. Sometimes it is still worth the risk as long as business is steady.

              it looks as if the 375 fell through the cracks on this 1 . i gota blame miller (that was hard to say )
              the spec 125 uses the ice-12c witch has a dedicated drag tip circled in red.(pic torch1)

              the spec 375 uses the ice25(old) and ice-25CX or ice-27C (new) no drag tip option. (pic also torch1)

              the spec 625 uses the ice40 with optional drag tip circled in red (pic torch2)

              seems odd that miller would only forget this 1 cutter????

              if it helps any i prefer not using my drag tip as it is harder to watch the arc and stay on line ,i usualy use the back of my other had to stedy the torch to keep a constant standoff.the wheels work good for long strait cuts but not much else. good lucl and happy cutting

              sory we wernt much help

                fyi

                The Spectrum has only one tip designed for it. It is a drag tip but will cut thicker and better with a 1/16 standoff. Even the ratings are listed for both.
                3/8" quality cut with drag or 1/2" with standoff.

                A-

                  thanks ASKANDY

                  it didnt seem right miller would have missed it. just not real clear in the sails catalog, even checked the 2005 catalog. i'm guessing it is clearer in the owners manual.
                  maybee his dealer should have made that clearer to him
                  thanks for the help
