There is another killer apps - for guys like you - It is called "NaviGates" - not a map or navigator - This helps you navigate GATES BELTS - find the one you need.
Looks like mostly auto - Vehicle, Vin, then Search by Keyword - store locater etc.
Might be able to find replacements at the machine and find a dealer. And it is another free app.
The other is a Miller welding calculator Mig solid, Mig flux, Stick, Tig
In stick (as example) - select Metal - and then what electrode you are using. Tells the range of current - for light metal and for heavy.
It is free.
