trainings_data.csv is acquired during the welding of a slope with an initial CTWD of 5 mm and a end CTWD of 30 mm.
eval_slope.csv is a repetion of the set-up used for trainings_data.csv.
eval_constant.csv uses a constant CTWD of 10 mm.
eval_lower_wire_feed.csv uses a reduced wire feed of 2.5 m/min.
