need tig welder advice
Hi
I am fairly adept at soldering, brazing and stick welding, but would now like to learn tig welding. What I have in mind is one of those inverter type welders which will do both stick and tig. Does anyone know which is a fairly modern book on 'how to tig weld at home' type of book? What I would like to to is read something to learn enough to make a good choice of machine. also , anyone has any preference for features or models of home tig welding machine The uses for this machine are a small amount of car bodywork (possibly) 1/8th thick or less aluminium and stainless. The stick part would be farm maintenance ( I have a good old fashioned stick welder anyway) many thanks Larry |

tig welding
for that thickness tig welding the smallest - and cheapest inverter will do fine.go to the library, there will be books there - free - on how to weld with tig but the best way is to practice. all the small inverters require striking to start where you'll find most books etc tend to assume you are using big posh machines so practice makes perfect.
you can get them for 100 +- quid so they are not that expensive, but you need to get an argon cylinder which when you've done the contract etc etc can be a bit pricy. you'll also need to buy guages and regulator for the bottle so the price starts to rise - invest if you will be using it alot otherwise get a mig - cheap and cheerfull, not as pretty as tig but ok. as i say there's no substtute for experience so if you're set on a tig, get all the gear and practice practice..it's not that hard if you can braize etc. |

forgot - you will need big and expensive tig welder and years of practice / tutoring to be able to weld alluminium nicely - stainless is easy and can be done on small inverter no probs. you need dc welder for ally mucho dosh, mucho skill required

I bought a nice tig outfit to teach myself to weld aluminum, not easy at all I would suggest a class, I can produce a good weld only about 10% of the time.

seems that to weld aluminium, you have to buy one that welds ac. These are expensive.

If you can gas weld with oxy/acetylene then you can TIG weld .
You will need to practise though and evening classes would be a good idea to set you on the right road . A 185 amp welder AC/DC with high frequency start should do the trick . It can be used for stick welding too and will handle all you might want to do as an amatuer . Avoid the cheap brands and look for models made by Lincoln ,Miller or the better brands in your country . If you don't need to weld aluminium then a DC welding machine will suffice . You will need a TIG torch and regulator for an argon cylinder. Don't buy used equipment unless you have seen it working. Good equipment is not cheap but it IS worth it if you want to do the job properly .

more info
http://www.millerwelds.com/education/TIGhandbook/ This is a very good site and you can read about all the Miller models . Lincoln stuff here http://www.lincolnelectric.com/ You don't need an inverter unless you really want to go down that route . Once you have mastered the art of TIG on mild steel , then you can start on stainless and finally aluminium which is fairly straightforward once you have the hang of it .

aluminium and its alloys are very hard to weld, especially on DIY kit. it takes the lads at work (aircraft repair) four years to learn, and then they might never get it. and if you think thats hard, try titanium!
steel on the other hand is pretty easy. to get kit able to weld alu will cost a lot to buy, but nearly any small welder will do 1/8 steel. TIG takes practice, have you cosidered a MIG set?

ah i see. it does look better, but i found MIG a bit easier. after welding a few expensive tungsten electrodes to my test pieces i gave up and went gasless MIG.
heres a question for you then.......... you buy a budget TIG set, it comes with some filler rods, a handset, AND A HANDHELD FACEMASK. how do you hold three things with two hands? please, i dont want to hear from any isle of wight sister shaggers wondering why ive only got two hands

Might have to bend the handle a bit . I've heard the raspberry flavoured ones are really good .

I have to admit i use a helmet type mask, with changeable filters plus plain glass for the spatter. ( necessary for brazing )
