TIG EQUIVALENT OF COATED WIRE IN GASLESS MIG
TIG EQUIVALENT OF COATED WIRE IN GASLESS MIG
(OP)
Jumping over to this forum to ask a quick question.
About 50 years ago, I saw an accessory for a stick welder which used 2 tungsten electrodes. It provided intense heat and/or light. I was considering buying same (to expose silkscreen emulsions) when another application came to mind.
Would I get a sound weld if I were to feed the coated electode, normally used in a stick welder, into the tungsten arc? Wouldn't this be the TIG equivalent of the coated wire trick used with gasless MIG welders?
(For those wondering why I'm asking, I'm an old man who can still weld pretty well with a torch, but shaking hands make me a very poor stick welder.)

You may be thinking of carbon arc welding. Try a google on this and you will find lots of information. Gasless MIG welding uses flux cored, not flux covered, wire.
If you have some spare change ($500-$700 or so) you ought to consider a used TIG welder. If you can gas weld, you can TIG weld. The rod is fed by hand just the same way.

I think all you would get trying to tig weld with a stick electrode is a mess. tig welding just doesn't need the flux, and it seems like it would just get in the way. Although the thought almost makes me want to try it to see what would happen. Anyway, I'm not sure what you are tring to do with that combination. If you are going to use a tig torch, why not just us an uncoated wire designe for the application?

I've only seen it in SS and it is a little tricky to weld as it produces a lot of slag.
I've heard that Kobelco has a flux coated CS wire.

If your main goal is to tig weld with a stick welder you have, it can be done, but arc starting is more difficult, and you will need to add sheidling gas aparatus.

There is an accessory, for an AC stick welder, which consists of a holder for 2 tungsten electrodes. This accessory is usually used to provide heat for bending or brazing or as a light source. I was planning on buying this accessory to provide a means of exposing photosensitive silkscreen emulsions when another use came to mind.
With a stick welder, an arc is established between the coated electrode and the material to be welded. As the electrode coating vaporizes, the released gas protects the weld long enough to prevent excessive oxidation.
So, instead of using the arc between the coated electode and the workpiece, why can't I use the arc generated by the tungsten electrodes and feed the coated electode into the weld in the same manner as the filler rod in TIG or oxy-acetylene welding? With either the conventional stick welder or the technique I'm proposing, there is, in close proximity, arc, filler metal, and the protective gas. Am I missing something?
(See an earlier post as to the "why bother" involved.)
