    Must be a Townsville thing, I lived there for 10 years & that is what I thought it was too but now I know otherwise.

    What do you reckon CHS is?

    Cliff,
    If you are after info on MIG welding try this site (and associated forum) http://www.mig-welding.co.uk/

    I been doing a bit of MIG welding lately and have found it a very useful site (even though it is based in the UK).

    If you do choose to use stick welding (I wouldn't) then here is a good tutorial http://www.aussieweld.com/arcwelding/index.htm
    Cheers.

    Vernon.

    Or what I was told and what I have read off other supplier sites is that RHS is both square and rectangular because its dimensions determine whether it is square or rectangular.
    the R actually supposedly means ROLLED....but then you probably know that anyway.

    So if we digress into naming conventions we have BAR which is both in rectangular and round forms in plain and deformed styles. BAR sections can be both hot rolled ie has scale and cold rolled or CRS which is cold rolled to form and is the expensive stuff that you get in various grades.

    Thanks Vernon.
    I had seen the 2nd site & had posted a link to it on here before (but I can't find it now. )

    I'll have a look at the UK one over the next couple of days.

    Life in this chookhouse is far too lively at present to spend in at a computer.
    We have friends staying for the weekend & the concreters have just made an enormous red mess of our back yard.

    Cliff,the term inverter refers to the power source for new generation Stick,Tig and Mig welding machines.The transformer is replaced with a transistorised circuit which changes (inverts) the incoming frequency.In Oz it is 50 Hz,the inverter raises the current frequency in the multiple of thousands range.

    It allows a whole new series of different variable control control ver the welding arc intensity and arc stability dependent on the mode, be it stick,tig or mig.

    Once a welder gets his grubby paws on an inverter the desire to continue with a transformer model diminishes.

    Default iNLETTING QUESTION

    Hi Cliff


    The inletting is basically plunge cutting .One needs a steady hand.The 1mm blade cuts rapidly and is easy to position. Visor and eye protection naturally.The angle grinder is held with 2 hands.

    The example piece is a section of angle iron 40 x 3 which has a piece of 20 x 20 x 1mm furniture tube inletted.

    For easy inletting in an angle or box section.
    follow the pics.

    Pic 1 Marked out with a cut- notice the 1mm kerf.

    Pic 2 Cut out

    Pic 3 Tacked up

    Pic 4 Welded and Ground
