    I would like to play around with TIG on my current set up. I have Argon and flow meter for the spool gun so what torch would I need to delve into the dark art of scratch TIG?

    A visit to @Richard. Before you get into bad habbits. (That's my plan once I'm set up.
    I have an rtech Tig torch in the garage actually.
    Kept meaning to did out how to make it fit my Thermal arc but haven't had a chance yet.
    Would that be of Interest

    A valved torch with a 35-50 dinse connection :)

    search "WP17V Tig Torch" and the first one on amazon will do what you need.

    scratch start TIG is annoying when you've used a real TIG welder, but doing it your way will be cheap and fun. If you can get a lift-arc machine it makes life a lot nicer, although still annoying.

    Ok I took the plunge and took the offer of the WP26 torch as shown above (many thanks) As this is just to dip my toe in the world of scratch tig on a hobby basis, can someone suggest a list of consumables and filler rods (steel and Ali) to get me started on a very "Newbie" basis. There are some small consumable kits on Amazon and the like but not sure what I will need so loathed to buy the full kit from R-Tech - what size tungsten, filler rods etc. All sugestions gratefully received.

    Wrong thread btw, but none the less, i was using a 1.6mm tungsten, and some lengths of 0.8 mm mig wire and 1mm gas welding rods as filler rods. Thats about all you need to get busy. a spare tungsten would have come in handy, but when i " dipped the tip" i merely took out the tungsten and reground it.Although a few spares would be handy, i never damaged a ceramic or trashed a tungsten.I you put some half metre lengths of mig wire in the vice and spin it a couple of times with the cordless drill, it straightens it.

    erm... that WP26 torch shown above is not a valved torch, and therefore simply no good for your welder :( you'll have to faff about with connections and a new torch head with a valve etc...

    A few things I would reccomend for beginning:

    1. Start out on some thick-ish material. 2mm minimum, ideally 3mm... you're almost guaranteed to overheat anything thinner, and it lets you get on with making nice beads instead of cursing, until you get the hang of it.

    2. Don't be cheap, buy some 1.6mm wire. You can't physically feed 0.8mm wire fast enough to keep up with any sensible job, and you can barely hold the stuff still in a gloved hand never mind feed it. Yes MIG wire will do it... but I thought you wanted to have a good time, and make some nice beads, not a miserable time :) 1kg of wire will last you a good long time and it's not expensive. It will also do most every job that you can think of.

    no.5 ceramic will do just fine, No.7 is my preference for most jobs if I don't think about it.

    Ah all becomes clear now, I had assumed wrongly it was a valved torch - so my mistake - and thank you for pointing this out- its a steep learning curve sometimes.:ashamed::ashamed:
