to me that seems so stupid id rather set it roughly to where i think it needs to be and then adjust it to get a better flow of weldIf it is the MIG it does not show welding current until welding, think I have asked this before, a bit awkward I know, but for Mig you don't set current, on MMA you need to strike the arc and try and set, or weld and get someone else to set and mark the dial.
As said a biot awkward but you will get used to it soon.
I have used mine for MIG and Stick and performs well.
