Any TIG machine with AC/DC and high frequency arc starting (like any of Everlast's AC/DC TIG inverter offerings) is going to be able to basically handle welding aluminum. If doing a lot of aluminum...

FYI, the wheel repair shop I did a lot of wheel weld repairs for wouldn't have taken on a weld repair in the location you describe, (which sounds like it is by the hub - where the wheel fasteners...

Impressive, guys. Looks like you have taken a lot of the forum members' feedback into consideration on a number of counts, and I think it's going to show with a very popular product! We're really...

Rectified, look at this thread:

Mike -

The scotchbrite hand pads are cheap. I'm pretty sure I paid less than $1 each last time I stocked up. Look for a place that buys them by the large box and sells the individually out of...

That does look pretty good. I'll often use a scotchbrite hand pad to similar effect:
9845
...it leaves a nice "grain" pattern on both aluminum and stainless without rusting. (Just rub in the...

I like Mr. TIG. So what if Jody's videos are better? That's a pretty high standard to be compared against. There is still good info, and useful things to be learned from watching Mr. TIG, IMO. ...

I used pulsing (particularly on DC; I am much more hesitant to bother with it on AC applications) when I want to reduce heat input. Occasionally, I specifically avoid using pulsing (such as when I...

Solar Flux "B" is made for that purpose, at least for stainless steel applications. (I've not tried it on mild steel but would be surprised if it didn't work simiarly.) However, it does leave...

Nice work... making intake manifolds with the TIG welding processes works out very well! :)

(I once tried making one with the oxy-acetylene welding process, which was a big mistake.)

That's pretty slick looking... nice work! Got any overall picture of the saw mounted into it, ready to a cut?

Solar flux "B" is a good way to go for shielding the back side with a repair like this, IMO. Nice work!

How much force did it take to get the tube back into alignment? Looks like potentially a good repair (depending on what was happening on the inside and what the original cause of the fracture was.)...

An angle grinder with a grinding disc should do the trick for mill scale removal a lot more quickly than with a flap wheel, (and without the hazards of using an acid to pickle it away.)

For larger...

I'm speaking mostly from an autocross racing perspective here (which is definitely paved, and turns both directions), but I've always admired the performance potential of the 125cc shifter karts. ...

Sounds like a very interesting compressor option. How much did that compressor cost? And which tank configuration did you end up getting?

The main thing I dislike about my current compressor (a...

A good brazing bond is very strong. A typical reason to braze is that it may allow less distortion of the workpiece than welding (due to e.g., not needing to inputs as much heat energy into the...

I use Lennox neo-type, (in 1/2" x .025") which is stocked by my local "sharp shop", and sold at a reasonable price by the foot, in a variety of teeth pitches. I have tried 24 teeth per inch, and 18...

lph??? You mean lpm, right? (If so, I agree to try 7 lpm, because 14 lpm will likely cause turbulence and draft in air with that size cup.)

It looks like you've got some workpiece overheating...

I've been studying the AC frequency and the pulse circuits in my Super200P a bit lately, and basically found that indeed, they operate completely independently of each other. This matches what I've...

Mark and Janne, thanks for sharing the Mosfet machine schematics! These are very useful for helping to understanding these machines better! (And finally, I now know what some of those Trimpots in my...

Hooda - if the end of your stud is recessed, you shouldn't have much problem with "capping" the aluminum over it using TIG. If you want to try and save the finish of the stud (I'm guessing is zinc,...

If you are really able to back the current off with your footpedal (while still maintaining the arc) sufficiently so that the puddle completely solidifies, while also having the machine set up to...

Congrats on the 250EX purchase.

I could see some spark being audible (and maybe visible there) when the arc starting (also known as "high frequency") is working, but this should normally *not*...

This guy gets good results on narrow angle stainless merge collector with what looks like something in the area of a #6-#7 gas lens, and maybe a cup width's worth of stickout; I'd say. (see his...
