Re: TIG Helmet

Y'know, my old-school #10 glass lens has NEVER flashed me unexpectedly... Technology has value, but it comes with trade-offs.

Re: My first welds... Whaddyu guys think?

Check your post-flow settting. The pimple trying to pop up at the end of the welds is porosity from white-hot steel coming in contact with oxygen in the air. make sure you try to hold a arc length equal to the tungsten diameter and hold the torch there for a few seconds after extinguishing the arc....

Re: R-Stamp questions...

Question about the ceramic backing.... Do you ever have any trouble with porosity when using ceramic backing? I ask because we used it a lot but I was always questioning the way they stored the stuff and if it was picking up moisture or not. We had random bouts with porosity and I blamed it on the b...

Re: TIG Helmet

If you got arc flash it would feel like you had rubbed sand into your eyes. But the failure of the hood to darken is just like looking at a bright light. Or staring at a flashlight etc. Not actual arc flash. I agree.... the more expensive shields have more than one or two sensors that help in low l...

Just seeing spots after welding is not flash burn....that is an over exposure to the yellow frequency light waves, like when Oxy/fuel cutting without a dark enough shade lens.

You're getting it....something else that helps is to keep a tight fit between the plates, clamp them down tight, if need be.

Re: Trouble with butt-weld penetration

Ps, one more thing i'm interested in..... Why do more than one ''pass''? If you are asking about fillet welds, then the answer is...a fillet weld is measured but the length of the legs and then the throat. If a drawing calls for a 5/8" fillet weld, you obviously cannot put that down in one pas...

How close?...far enough away to keep from melting the front of your shield, while keeping your head out of the plume of fumes.

I'm going to agree with welding mike.....aluminum can be welded with the welder you mentioned but it will need to be preheated just prior to welding to make the machine feel larger than it is(some grades of aluminum will not be happy with the extra heat). You really do need the extra amperage capaci...
