I am relatively new to this site, and have read quite a few posts concerning bead shaping while welding aluminum with the newer machines (inverters). Most offer not only control over + and - balance of the AC square wave but also the power to alter the normal 60 Hertz input to a variable Hertz on the output side of the machine, thus arc shaping.
I bought my Lincoln Square Wave Tig 355 in 1995. Correct me if I am wrong, Miller came out just after that period of time with the Aerowave which had the adjustable Hz. output and an extra $3000.00 list price.
My questions are, what am I missing without the ‘arc shaping’ capability of the newer machines? What is the realistic advantage, or benefit you gain from having this control?
I am interested in your experiences when this feature has come in handy or as a necessity.
Thank you in advance for your response.
