I have noticed that the size selection of tungsten from an inverter machine compared to a transformer is quite different and figured worth sharing for others learning to TIG. On the inverter I found out (thanks to Shovelon) that u can use a large tungsten, say 1/8" on just about any thickness metal. Due to the pointed tungsten and very little balling at the end...I had been puzzled by Zapster's use of 1/16 tungsten for relatively hi current welding. However I discovered that due to the traditional 1 1/2 times the tungsten diameter ball that forms on AC transformers I could not weld anyway near as thin stock as I could on an inverter. Thus I had to drop down a couple of sizes in electrode... Seems that some of the reference charts for tig are totally off depending what type of machine they are written for. Also foe example the Miller tig calculator claims a crazy 1/4" tungsten and filler for 1/2 alunimum tig welding and requires 3 passes. That is crazy for either machine. Now I just set the dial at what I think the max current I need will be, run a few test beads to dial in the pedal sensitivity and current by watching the puddle. Same thing with the gas. Turn down as much as I can without getting contamination...Tiger Sales: AHP Distributor www.tigersalesco.comAHP200x; AHP 160ST; MM350P, Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.

Reply:1/16" is pretty useless for most everything. They really suck to work with compared to 3/32.Welding/Fab Pics: www.UtahWeld.com
Reply:heh, I thought I read u were using 1/16 a lot, I am not greedy and have plenty of 1/16 already so I will pass butt thanks for the offer...Tiger Sales: AHP Distributor www.tigersalesco.comAHP200x; AHP 160ST; MM350P, Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.

Reply:Bump!Question: Inverter machine, DC only, so TIGging steel & SS. Rank beginner. Don't want to invest in a stack of tungsten. Mostly for learning at first, maybe 1/4" down to sheet... probably not Zaps' aluminum foil any time soon, though...3/32?

Reply:Cool, thanks all.I've heard good things about the rare earth options... I know they are non-traditional... Any opinions? I realize they are different by manufacturer, so I guess that enters into it.K

Reply:I am using thoriated .040 and 1/16 on down to 16ga up to 1/8" steel. Haven't even tried the 3/32" yet. I used 3/32 on 1/4" plate on the limited intro I got at the local Votec.Any thoughts on matching tungsten size to material vs amps for the transformer machines? I'm limited on the tapped voltage down to 35A on the Lincoln.I just ordered some lanathanted to try it here:https://weldingsupply.securesites.ne...F:OR:terms::PNThe prices are good, especially on house brand filler rod, but they are a bit high on the shipping.
