It could inputs in drop down boxes for MIG, TIG, parameters. Workpiece (stainless, ferrous, aluminum, titanium, etc.), thickness, current and voltage settings, wire diameter, type of wire (steel, flux-cored), for TIG electrode diameter, cup size, gas flow, maybe even waveform choice. For stick, rod type and diameter and current settings for different materials.
Known or past used data could be stored and accessed for future use.
I am going to contact LE and Miller and see what they may have in the works. Miller has something like this on their site, but it would be nice to have it on the Droid.
