This one is going to open a whole can of worms,but here we go. A machine shows the amps and volts on the rectifier or what ever. This is the interesting bit,how does the welder know his amps and volts when he is behind a screen?
Correct. Interesting don`t you think.Let`s say that you have a procedure of 220A at 22v,how do you know you`re getting that.+/-10%?He doesn't, he shouts up or down a bit to one of his muckers.

Maybe we can get a machine that talks to you,just like a robot...................YOU HAVE 150A AT 22V.....TOO LOW!Some machines have a "hold" feature which displays the parameters for a few seconds after the trigger is released, if not then as Bob says, you need to recruit a willing accomplice to tell you what it's reading (or of course, in this modern age you could always record it on your phone camera).
I fully understand yes, there is a facility on the torch for reading Amps/Volts,the danger is looking away from your mask to look at the torch head there is a risk of a flash.That reminds me,
There was a post a while ago from a guy that was developing a helmet with a heads-up-display to show that kind of information.
I think he was drawing people in by offering to let us test the units but I'm not sure if he ever came back once his questions had been answered!
Quite a few welders have displays on the torches now, plenty of industrial kit has a socket for a remote control/display.
Some *(if not many) can also interface to record all the details during the weld process including stuff like reading the induction and wire feed rates so more than just amps & volts.
Migatronic industrial units have a network socket so the important guys can set the weld parameters from the office then the software records exactly what the guy on the shop floor is doing and red flag a job if he goes out of spec on it.
I have a cebora that has a usb socket.
I can set up a weld parameter/program on that and lock the machine to that program.
If anything goes outside the settings during the weld run it will stop and lockdown.
It also has a rs232 port which can stream out the live data somehow.
Not something I use but if you were doing something that needed that level of control over the welds there is plenty of tech available in the welders to make sure you get it

Turn the machine to 22v (or closest voltage tap if you have a transformer) and ballpark wire speed, do a weld, look at amps hold reading, turn it up or down a bit to suitCorrect.
