You are using 3/16 tungsten, are you sure?

That huge stick, you dont need that big anywhere in automotive welding.

You get by every task with 1/16 (1.6mm) and 3/32 (2.4mm).

Highest amps 250A, I ever used was when welding an 3/4" 8"x10" plate to intake manifold. But not every day you fabricate a Roots-blower intake manifold.

Sorry... you are right... 3/32... not 3/16!!

I buy NON Chlorinated brake clean by the CASE ($1.99 a can if you catch it on sale) to shoot down inside stuff like this BEFORE welding. And either you can drill a small escape hole -- or leave the last tiny bit open - let it all cool down and go back and touch it up.

I learned one new thing today. thanks Greg.
Now on ward and upward...

Don't remember if I threw in this .02 about the cleaning comment. Greg mentioned non-clorinated brake cleaner. I started buying acetone in gallon cans and keeping a small squeeze bottle on my welder cart. That way I have a small supply of acetone that I can use to clean things before welding. Squeeze bottle helps with more accurate delivery and less waste.

Very good info. The description and demonstration of long arc length looks exactly like the problem I'm having.

I just picked up a used JMR tube notcher so I have more welding challenges and practice are on the horizon for this winter. Here's the first attempt with .75" OD 4130 tubing.

Didn't take long to notice 4130 welds much nicer than some of the junk I've been practicing with! Now I need to find a source of affordable 4130 practice scrap. That stuff is :G-Dub:
