Hi guys,
I'm currently tossing up the thought of finally treating myself to a cheap AC/DC TIG welder, and there's one at a great price which only lacks a couple of features that the more expensive unit contains. Having next to no experience with a TIG, I was wondering if I could get some clarification, and some feedback as to what would be typically used more, whether it's worthwhile etc.
The bargain machine's list of features is as follows:
Multifunction: Tig Ac/Dc, Tig Dc, Stick/MMA
Foot pedal Control: Foot controller for those precision required applications (Included)
Extended Ac Balance Control: Adjust the balance between penetration and cleaning for Aluminium
Pre & Post Flow: Prevent oxidation of weld metal by pre and post gas flow
Advanced Squarewave: Improves weldability with excellent puddle control
High Frequency Start: Non-Contact Tig arc starting
The next unit up sings about all of that, with these extra capabilities:
Pulsing: Reduce heat input & distortion when welding thin metals
Down Slope: Slope down the amperage to prevent crater cracking
2T & 4T Trigger Latching: Use when welding for long periods of time
As a beginner (Who genuinely wishes to pursue a career in welding, oh to find a mature age apprenticeship) would I potentially have need of these features? Or are they more "nice to have" for when you've done it long enough, understand what's happening, and it's nice to let the machine do that bit of hard work for you (ie can be replicated with technique).
Mild steel is my primary metal, with the obvious wish to build knowledge and skill with aluminium and stainless.
Thanks!
