What makes the TB 275 better than the 325? Aren't they essentially the same machine?

I remember when the 'new' trailblazers came out the 275 had all of the same options as the 325 (model numbers). Now I see they have discontinued most of the original 275 models w/ options... Either Miller...

Sorry to see it go...

Unless there is a shortage on available input power on your end, IMO you are CRAZY not to buy the current model especially with all of the rebates. I would be curious to hear someone from Miller compare the PROS/CONS of the previous unit and the new inverter!

I second Danny's suggestions. Spot on.

There really isn't enough pressure to worry about... The quick connects are common accessories for the suitcase feeders.

What I don't understand is the use of the 'pigtail'. The quick connects usually fit right into the fitting on the back of the machine (inert gas 5/8" male with a...

The surges are real... We've done tests with balloons and flow rate testers at the end of the guns. Like the poster above said, flow meters deliver the flow rate at a preset pressure like 50 or 60PSI and use a small restricting orifice to regulate the flow. When the flow stops, the line between the...

I would simply call your LWS and request a gas surge analysis. They more than likely will do this for you and for free - hoping you buy the appropriate equipment to solve the problem of course. YES you are using / paying for more gas than necessary. Victor and Harris both make products that will reduce...

It will do anything you want...

The internet is full of bad information. The 350P is perfect for what you want to do.

A low hydrogen rated (just like 7018 rod) dual shield wire is easily accessible (to the guy who told you to stick weld to be safe). Make sure you get a 4...

No doubt about it. As a salesman at a LWS, I have to call manufacturer's customer service departments several times per day. Miller is HANDS DOWN top notch. That said, thier distributor support system is also second to none. That all trickles down to a great end-user experience.

Not much more info there than i gave here, but that's the original comment.

Very possible. Like I said, they may have the issue fixed, OR they saw a defect in his machine ONLY. But the message to him was clear: Your machine cannot do 400hz. He is now a happy owner of a 350...

Might have been me...

On Weldingtipsandtricks... I briefly related the experience of a customer who bought one when they were initially offered. He ran 400HZ and fried a board... Ran 400HZ again and fired the new board. Miller took the machine back and did indeed agree that it was a design...

I've had this discussion with a few other people... Updating the 211 to an inverter would certainly be 'new' but i would argue - not so 'improved'. If you are thinking about buying a 211, I would so so BEFORE they change it.

[johnnyg340]

By calibrated I mean each gas has a different density in atmosphere. That determines how much gas it takes to move the ball or needle on a given regulator. CO2 is 'heavier' than Argon, so you can imagine it changes the way it moves the needle or ball. Like I said, the difference may only be 10% either...

[johnnyg340]

Consider too the different densities of the gasses. Flowmeters are calibrated for the specific gas service, but for most applications, 99% of the time the difference is negligible. However, if you are working off a WPS this would matter.

[johnnyg340]

To me, i can only think of a few reasons to buy an inverter:
1) POWER CONSUMPTION
2) DIGITAL (SMOOTHER ARC / ADVANCED CONTROLS)
3) WEIGHT

So number 1 for me doesn't matter, at least not with a 211. On 220v its drawing around 25 amps. Most shops / garages with 220 service...
