Re: Miller three phase welder questions

Once you posted a pic, I realized they my TIG welder is built on the same frame, so a lot of things are similar.

Re: Miller three phase welder questions

Facing the front of the machine, the right side cover comes off to connect the power cord. There should be something in there about 240 or 480 hookup.

Re: Miller three phase welder questions

Post a pic of the front panel and it will be easy to tell you how to test it. Just guessing without seeing it, If it has a switch for the high frequency make sure it is on, and flip the "Contactor" switch to "Remote. Power up the welder and just flip the "Contactor"switch to "Standard" for a second ...

Re: Self centering vise

I can't really imagine any advantage to a self centering vise in a mill. I always work from one corner of the fixed jaw on a milling vise as the dials are zero'ed there and it remains constant. By doing that, you are always working in a positive direction from zero. Being zero'ed on a center point b...

Re: Spin Grinding Wheel Before Starting

External grinding hard chrome on 3 1/4" dia. x 30" long tubing. Huge coolant flow to keep it from moving around from the small amount of localized heat created by the wheel contact. Grinding small areas, or solid parts with hard chrome is wonderful, large areas on relatively thin wall tubing with a ...

Re: Spin Grinding Wheel Before Starting

I've always found that a wheel grinds like it feels. I usually only do it when a dress is needed prior to a finish pass on something that matters. The wheel grinds good after dress, (as far as surface finish) then gets real good, then starts to slowly go away. The trick is to time it so that the whe...

Re: Spin Grinding Wheel Before Starting

As to it helping save a fresh wheel dressing ... I've been wrong many many times but the little I learned and everything I have read has told me that the only real way to keep a freshly dressed wheel exactly how you dressed it is to keep the darn thing spinning . And that is exactly what I do when ...

Re: Spin Grinding Wheel Before Starting

Perhaps I led this astray by using the word "slipping", as some appear to be visualizing the adapter spinning in the wheel. What I am referring to is an immeasurable nearly undetectable pattern in the finish of the part being ground as opposed to the finish of a part ground with a wheel dressed just...

Re: Spin Grinding Wheel Before Starting

Been spinning the wheel on one of my surface grinders since I have owned it. I use 8" wheels and it is 3/4 hp. I discovered exactly what is being described in the previous post. Stopping the wheel and re-starting it would render a wheel that no longer ran true due to the adapter slipping on the blot...
