So we got a new machine at work for welding 1/8 tubing and adding decorative endcaps. The millermatic 350p is a beast of a machine it has a setting called r-in and I can’t seem to figure out its purpose can someone help describe it or what it does?next to the chart it shows a diagram from 0-100 with a arc and gas symbol but it’s the same symbol used on arc control so I’m confused?

It’s the parameter for setting Run In speed of the wire.

A buddy who owns a body shop bought the same machine to weld the modern ally bodied vehicles. Miller has a few software packs that apparently are dead-on perfect for this. Yeah, 350 amps to weld 0.040 ally is overkill, but the advanced wave control and pulse parameters make it really, really easy to weld and not blow out the panel.

I did a repair for him while they were awaiting the machine, and heck I think I was at 39 amps and nervous as a Politican in a Confessional.

I'm guessing you mean 1/8" wall tubing...

You really ought to call Miller Tech support directly. Make sure the machine is registered for warranty while on the phone with them. They can be extremely helpful with configuration settings for many of their machines. You don’t get some “switchboard operator” answering your questions from a placard of stock responses. You get to speak with a real live, “knows a lot” person who happens to also know the specific machine you’re calling about. Almost like having a tutor looking over your shoulder
