Miller Weld Setting Calculator 4+

For a free app it covers the basics nicely, though it would be good if it covered more metal types (like titanium). The data display isn't consistent between welding processes which is a little confusing. Being a mostly American orientated app it's metric data is a bit inconsistent too, not appearing at all for TIG weld data and being straight conversions from imperial metal thickness standards rather than typical metric sizes - eg. 12ga/2.6mm instead of 3mm, 3/16"/4.8mm instead of 5mm, and so on. Gas rates are also in CFH (cubic feet per hour) or PSI rather than L/min (litres per minute) which is more typical in metric countries. Again, for a free app they're minor gripes, but if it had a proper "metric" mode that'd be something I'd pay folding money for.

So why are some measurements provided in imperial and metric and others only in imperial? I know miller is American but you are the only developed country using imperial. And the fact you have it in some options and not others is a little frustrating.

Also as I move through the menus it doesn’t actually wait for me to hit the ‘next’ button to progress. As soon as I stop the up or down roll on the selector the app just assumes I’m done and off we go to the next menu. This is more than annoying especially in the mmaw menu where the selection of rods is quite long so you have to stop sliding to move your finger up/down to continue sliding but are suddenly faced with having to go back a menu because it’s decided you are ready to progress.

If you were to improve the app I would say have an option to have imperial or metric measurements as an option in a settings menu and fix the ‘app deciding I’m ready to progress faster than a teen boy in his first time’ bug.

This is a great app (considering it’s free) to get you in the “ballpark”.
