    Default TIG Welding - Any Experts Here?

    Hi all

    I would like to learn how to weld aluminium. I believe the best way to do this is with a TIG welder, this would also give versatility to weld other metals as well. Apparently TIG welding isn't easy (or so i'm told) and it's been suggested that I learn how to arc weld first. Being a bit of a 'dive in at the deep end' sort of person I see it as a bit of a waste of time and effort learning how to arc weld first. I would prefer just to get stuck into what I actually want to do and learn straight from there.

    However, the first obstacle I have to overcome is what TIG welder to buy, there's just so much selection out there. I've read some stuff online and been told I need an inverter type preferably around 200amp. I've also been told to get an AC/DC model with pulse and also a foot pedal. I saw this one on eBay that seems to tick most of the boxes http://www.ebay.co.uk/itm/WELDER-STA...item234074e438

    Anyone here got any advice on what are good machines?

    Cheers

    Hi Jem
    I would agree that learning arc welding is a waste of time. Arc has only 2 common points with TIG. Its used to join metal by fusing and its powered by electricity.
    If you were to learn another discipline first I would say it would be gas welding, as with both you are melting a filler into the joint using a 'flame' provided by either burning gas or in the case of TIG provided by the plasma in the electric discharge.
    TIG however is the only form of welding I have not tried and is, Im sure a challenge but then so is gas or MIG welding. I think the problem with Ally is that the material itself can be 'interesting' to deal with. As TIG will weld stainless I would say you could start by learing how to TIG weld stainless first. Then once you have got the hang of how the welding process works you will be able to progress to ally while already knowing what you are doing with the machine and the general way it responds and you wont be trying to learn two things at once.
    Cant advise on the welder but maybe Smog is a good person to hit up on this as Im certain he can TIG and may know a little more than bugger all.

    The hand motions for gas welding are similar to TIG welding and a gas welding set-up is much less than a TIG welder that will weld aluminum.

    You can also gas weld or braze aluminum.

    If your objective is just to learn how to TIG weld aluminum, you need a machine that has a high frequency AC capability. TIG welding with a DC machine is much more difficult and requires helium shield gas.

    The size of the TIG welding depends on what you intend to weld and what thickness.

    I would actually recommend learning how to TIG weld steel first. A DC inverter is much less expensive than a welder capable of welding aluminum.

    I found this forum helpful when I was buying a mig welder. They also discuss tig welding.

    Moderately thick Aluminum can be brazed with the right gas torch, rod, and flux. I have a friend who brazes his own 19" rack chassis work. Worth looking into because TIG, while beautiful and ultra useful, can be a pain to acquire. The required work prep usually is very involved.

    You should ask this guy.. he does it for a living incase you want to find the best solutions. His favourite happens to be TIG welding: https://twitter.com/KevinCaronArt
    He also has a youtube page covering all kinds of welding, troubles you might come by and tips: https://www.youtube.com/channel/UCqT...bswxqYcG60VPGQ

    lead burning is very similar to tig as well. I have just started doing tig at work. I have had no training on tig, however my experience gas made it pretty easy.
    As the boys have said I started on stainless. It would be good to study the theory so you know how to setup the machine and prep the work.
