It will work all the way down to under 1 amp. Zap can prove it with the pop can he welded
Only down side is if u get it too low on amps for to long the weld could blow apart so be careful
I usually use 3/32 for about everything... but recently had to weld some heavy stuff and swapped to 1/8"
gotta say, I like it.
been too lazy to swap it out and it seems to work fine for .125 also...
What is the lowest amps I can use with 1/8" tungsten ?
any downside?
I understand a tungsten size too small for the amps... but what about bigger?

1/8 is pretty much all I use, makes it easy when I have to order more. I have switched over to the Diamond Ground Products tri mix for almost everything now, they have an awesome Wolfram Alustar for aluminum if you have a transformer machine. I have smaller sizes if I need to get in tight places with lower amps.

I've done coke cans on 1/8" electrode.
Downside...cost...wider arc, unless it's a very very fine point and harder starts

looks like you could run a second pass over the tubing. You’ll get a little more practice in also
In automated welding at low amps arc wander is a major concern even if ground to a sharp point.
It costs more, grinding takes a lot more. 3/32 is enough for most jobs, and it is no big thing to switch sizes. I've made my point before that grinding puts a lot of scratches on a tungsten, this makes for erratic arc. An 1/8" tungsten needs longer grind.
I've heard something about tungsten needing a given level of amp density to get a small predictable arc coming off the point. I've found a big tungsten when at very low amps tends to arc sideways, not off the tip.
When filling rust holes on some antique automobile lamps, I went down to .045 tungsten with very good control.
An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
That’s a nice edge weld John.
No problem Alfonso
John,
how did you cut out the fancy base for the mount?
Thanks
Looks nice. Iron butterfly comes to mind for the base!
