    You must be made of money.

      Nope, I work at a school (a charter school at that), so you know I ain't rich, lol. Y'all make more money that I do, for sure. I just control all my own expenses exactly as I see fit, so I get to buy the toys that I want.

          Thinking of getting an HTP ProPulse 200. I had to put my name on their waiting list as every single shipment gets sold out before it hits the US shores!

            I have seen that machine only online. Looks pretty fancy. Synergetic pulse...whatever the **** that is....all sorts of preinstalled settings. Supposed to weld aluminum pretty nice.

              I'll probable get flamed, I do own a 211 and Hypertherm 45 but the new HF units intrigue me. I kinda crapped when I was in there and seen them. The youtube reviews are kinda impressive along with the HTP's

                Good to know

                  Oscar,

                  I am curious have you tried running a roll of Hobart Brothers .030 HB-28 on your 211 ? The reason I ask, is because .030 HB-28 has turned out to be the nicest running .030 wire I've tried on my Multimatic 215, and based on the You Tube videos I've seen on the inverter based 211, the 215 and 211 have very similar if not identical short arc characteristics.

                    Danny, no I have not tried that wire. I still have 3 10-lb spools of 0.023", 0.030", & 0.035" wire that I need to finish before I contemplate buying more wire. These spools are some chinese-off-brand-private-label wire kind of thing, but even then, they run pretty good. Come to think of it, yes I have tried that Hobart wire! LOL. I just remembered the machine came with a roll of it and used it up first. I've also used HTP wire in the 211 we have at my work, and from what I can tell, it runs OK as well. I haven't tried many different wires as you can tell, but in my mind's eye I compare it to the welds laid down by weldors like Jody from Welding Tips & Tricks, and what not. Seems to run OK, even though some don't like it at all.

                      Looks like I dodged a bullet (so far, anyway) - used my new mm211 for the first time yesterday tacking/welding out a "handtruck on steroids" cart for the welder - remembered your drive roll woes and checked mine - runs straight as a die with normal roll pressure. Knocking on wood.... Steve

                        The only threads I can remember where a liner solved a problem was because it was kinked, not because it was "dirty." I'd love to be educated on this subject. I've somehow missed it.
                        Sorry I missed this post. When the liner gets dirty with shop dust, rust from wire, wire lube etc the machine spits and sputters. So the operator cranks down a little more on the drive rolls. New machines have a scale on the drive roll tension. 1-4. when you get to 3 it is recommended to change the liner.
                        So when you get too much tension it causes the board to pull too many amps. There is no protection on the board from the motor pulling too many amps. I've seen customers put washers in the tensioner to increase tension or crank them tight with pliers. if you notice you have your drive rolls cranked down all the way you are putting way too much pressure on your PC Board. Every welding supply company stocks liners for guns, just not in the same spot as consumables.

                          I actually keep a spare liner in the bottom drawer of one of my tools boxes, although I've never used it. To me, it's good insurance. I don't want to get held up on a job if for some reason I drop something on the whip or somehow damage the liner on a Saturday afternoon while trying to get a job done by Monday morning. They're $20. I have back up rolls of wire and gas cylinders, just my style I guess. I'm also the guy that buys two or three of the same filter so I have them when I need them. But I do still have an air filter for a 2006 Ford F-150 that I got rid of 8 years ago if anyone needs it. Brand new in the box, sitting on the shelf where I put it probably 9ish years ago. Oh, I also have spare head lamps for a 1998 BMW 318ti. Haven't had that car in a good long while....**** divorce lawyers....

                            Well what is one to do when the motor assembly itself is not operating in such a way that one cannot get away without using greater-than-normal tension, even with a brand new manufacturer replacement?

                              That's funny, keep it long enough you can call it "vintage"

                                Please provide cites for these claims. Indeed, the owner's manual for the current Millermatic 140 says to start at 3 and adjust as needed. Nothing is said about this tension being an indicator of liner condition.

                                I know liners are stocked. It was my point that they are not hawked like consumables.

                                When you say "customers," are you referring to people to whom you sell liners?
