Airbags local store ordered 10# for me, total including tax and the ever present 'HazMat' surcharge was around $73. Took 5-7 days to come in, no ship charge.

It's wholly common with 4043 filler, excessive heat brings it out more.

If the DC background can be on, without any pulsing, do so. You'll need max. heat input. Pulsing reduces heat input. Can and should preheat with the torch, even if separately warming part up first-which helps. Play the torch up and down the cracked area to be tacked...to get it close to 'heat', whil...

on dynasty 350- I prefer ceriated for DC, the tri mix doesn't impress me .035 wall and using 3/32" OD tungsten? why not 1/16" OD? (as you're probably aware-the tungsten size will vary the arc characteristics, significantly-at the same machine settings.) -if your 200 has the 'blue lightning...

ditto sensitivity and delay adjustments
It's easy to intermittently block the sensors, especially with low buck helmets
that have only 2.

Is manifold magnetic?
(it looks like cast iron)

I want to start practicing Tig on some aluminum. I have to go see what the shop has for a tig machine but my question for now is I have some scrap aluminum. Not sure what grade it is but I am in a aviation maintenance unit so most likely 6061. So would I just use 6061 filler material or does that d...

Ya I went and got a 300 temp stick and 400 temp stick so I don't go over interpass temp, cause I will have to do 2 passes. They are 4 link bars, not horribly critical but still want to do it right. My concern about post heated that hot is distorting the threads. I disassembled the Hiem joint so I d...

Hi, welcome to the forum. First of all don't run off onto the pipe, it will definitely be considered stray arc strike and fail visual. It's ok to have a fish eye as long as the crater has no depth to it. Often you finish and what you think is a fish eye is actually standing a little proud. As you r...

Presuming this is DC.
Why are you using lanthiated rather than ceriated or thoriated for DC?
IMHO lanthiated works great for AC, but prefer ceriated/thoriated for DC.

Has anyone bought one of these expansions? What's your opinion of it? Or in general, can someone help me understand when you would want the ability? Zank uses it for pretty new stuff to minimize the cleaning zone: http://forum.weldingtipsandtricks.com/viewtopic.php?f=5&t=6391 Dave uses it for o...

This version with hose barbs added, goes in line in coolant hose.
In use for 18 years. Replaced cap o-ring once.

use an AL backer and let it be part of the shell, if at all possible. A larger mass copper, etc. heat sink block will help--but you'll need to immediately cool down with water spray and air blow off to stop distortion. Pics would say much, as others have mentioned. Need to find out at least the basi...

…….ummm…and you're certain that this shell is AL and not--SS?
I've done old Ford shells and they were SS.

I use one for final grinding--green wheels are soft, will groove, but good for clean grind.
I use an al oxide wheel for roughing and cleaning up--first.

A picture of the actual problem would detail much more than you've actually said and eliminate having to guess at what's going on. Did you sand or grind the steel, then acetone wipe? At the end of the weld bead is there a 'suck hole' a.k.a.--'crater'? This is caused by abruptly stopping the arc, rat...

-TIG would be more appropriate

Whoops! maybe the OP did TIG it….he needs to chime in

Stainless isn't/can't be anodized Contamination? -welding in open air at prop edge, lack of shielding gas, mixing air into puddle, no backup plate or purge gas damming, or solarflux backside coating -mig welding with (presumably) 75AR25Co2 instead of 98/2 or tri-mix doesn't help for corrosion protec...

Well it might not be stainless, I just assumed it was as he told me it was, how can I check? I just ran a magnet over it and the magnet sticks pretty solid, unlike the stainless keg I have, which only mildly attracts the magnet. So I'm guessing not stainless? And as for the possible coating, I did ...

First post, so go easy. I recently bought myself a 200A AC/DC inverter TIG welder, for various uses around my workshop. I've always had a MIG, but never a TIG and have never welded TIG until now. Anyway, I had some stainless tube lying around ... the stainless tube always ended up with a white/brow...

I know the other side was not shielded from atmosphere....just like the insides of all the tubes I have welded....there is push through. I know because I have scoped some of the tubes to look. Question is how much damage if any to the parent metal has taken place? These pieces{ .040" CrMo shee...
