Smallest Tungsten you use?

[fdcmiami]

Amp ranges and Dia's follow the same ratio and proportion of pipe sizes ,,,double the Dia and the pipe has 4 times the capacity,,,you can check this out by looking at the chart on the bottom of page 4 in the CK manual...http://www.ckworldwide.com/tech-4.pdf

there are several poster's that appear to be regular or semi-regular tig welders. i'll bet they aren't using .040 or .020. i am one of them. look at the tungsten grinders sold on ebay. if you want an .040 attachment it costs additional. recently someone posted that they do 90 percent of their welding with 3/32 tungsten. they were right on.

i use 3/32, 1/8th and on occasion 1/16th. if you have the money and want to experiment that's fine. too bad you need to buy a box because you will probably be looking at them for a long time. frankly i am amazed that so many use 1/16th tungsten but it's also true that many are just getting started welding. and this fixation with helium? what is up with that.

Exactly,,,I have a 250 EX and the 3/32 covers just about everything a fellow needs,,,have smaller electrodes,,but only as a curiousity,,experimentation is one thing ,,doing real work in the real world is another,,,not to say we all shouldn't endulge ourselves in some hobby type expermentation to learn things..

As far as Helium goes,,,it's a way to make a smaller machine preform like a bigger machine,,,which confirms my choice of machines in my own case,,I choose the 250 EX ,,,cause it's as much power as you can get sucking juice out of a 50 amp single phase power source,,,I don't use helium,,,but it's good to know how it functions in the welding process

same here. i just looked at the dog sculpture. if i was thinking about building small pieces like that i would be looking for specialty fixtures to make the welding easier. there are clamping systems made specifically for that type of work.

I use 3/32 for most things as well along with 1/16th here and there.... Most larger projects or welding repair.

This is what I am wanting a smaller tungsten for. 1/16th works but it would be better if I could pinpoint the arc better with a smaller tungsten and I would think at low amperage, the thinner tungsten would have better characteristics!?

Welding it and holding it in place is not a problem... I'm just wanting to control the arc and heat better with a smaller tungsten.

Yeah I looked at it too,,,I admire people who build things like that,,,don't have any artistic ability myself,,,more or a meat and potatoes type of guy,,straight forward mechanical stuff,,I understand...or at least try too...

How much can you simulate a thinner tungsten by grinding a narrower point - say point length three times diameter of tungsten? (but dull the very tip)

It works for me. I have ground a needle point on 1/16 and have never found anything small that it wouldn't work for. It's not hard to make a .060" wide bead and with practice probably half that. I know there is a whole different world for micro-welding with different tools and machines, but nothing I deal with.

A tungsten ground to a needle point will work at very low amps,,,the flattened end of a sharpened tungsten determines the amp capacity,,,don't flatten the end and it is liable to blow off and contaminate your weld,,,so depending on the flattened size on the end after sharpening you can increase the useable amp range,,this is shown in the chart on page 4 of the CK manual,,,,if you plan your sharpening profile you can make a larger tungsten do fine work,,,but remember not to use it for heavy work unless you flatten the point..the ratio of flattened area to tungsten dia is also shown on the chart..

I tried grinding it down and it helped, I'm just wanting to try the smaller tungsten to see how IT reacts.
This is all part of my learning to weld.....
