TIG properly known as GTAW gas tungsten arc welding, and MIG as GMAW gas metal arc welding both use hand held torches which supply a gas shield around the electrode (consumable electrode in MIG welding and non-consumed electrode in TIG). The electrode could be replaced with silver wire. These torches are readily available from welding supplies. > The ability to strike and maintain an arc in an inert atmosphere is far, far > easier than in free air. > > Ivan: My arc is very stabile as long as the distance between the tip of the > silver and the water is less that an inch or so (actually, this max distance > depends on how far I'm into the run) AND the conductivity of the water does > not get too high.

Roger Well, there are not enough hours in the day already so it will not be tomorrow ;-) Ivan. -- The silver-list is a moderated forum for discussion of colloidal silver.
