### 5/5 — WeldKit Pro is well worth the onetime fee

*2026-04-26*

WeldKit Pro is a very useful, straight forward, intuitive and easy to use. Just select your welding process, and some basic info about your intended weld, and it quickly calculates the recommended settings, and it even allows you to save your favorites, so you don’t have to recalculate routine processes. 

I wish I had WeldKit Pro way back when I was learning to weld.  

Mark the developer is very responsive, and open to suggestions.
