[TheForge] TIG welding

[Rich Maynard]

Hi all,

Just to briefly introduce myself - I'm a UK teacher, who does a bit of =
metalwork manufacturing and design in my spare time.

I have a 250 amp MIG welder that uses Argoshield as a shield gas at the =
moment, and access to a gas welding setup as well. However, I can't help =
feeling that TIG welding might produce neater results and make for less =
grinding afterwards, as well as offering the option to weld aluminium as =
well.

I don't really know much about it, though, and would appreciate some =
basic info on the subject. I've had a look around at some machines in =
catalogues, and one difference between the cheaper models is 'scratch =
starting' and 'HF starting'. Would this make a huge difference; is it =
worth the extra cash? Could I weld aluminium with the cheaper scratch =
start models?

Any info would be appreciated,

Rich.
