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.
