Sure but if the system can get your arc length, work angle, travel angle and travel speed dialed and consistent before you even plug in a real welder that's a decent increase in the throughput of a vocational facility with a given number of welding stations because now a fraction of the training can be performed in the classroom.

It'll never match the muscle memory. Practicing welding isn't that expensive either...

After the safety courses you're never in the classroom. You should always be behind the stick with an instructor.

It really only takes a summer in the barn to learn how to weld.

Just put in 100 hours or so and you're good. 10000 and you're a pro, just like any trade, including programming.

It doesn't need to match muscle memory. It needs to lop off the first 10-20hr of actual welding where the instructor runs from booth to booth telling people to correct their arc length, angles and speed thereby increasing the efficiency by which welders can be trained.
