Contact-Tube-to-Working-Distance slopes with Gas-Metal-Arc-Welding

Voltage and current signal during Gas-Metal-Arc-Welding. Measurement Data acquiered using National Instruments USB-6361. Current was converted using a "Chauvin Arnoux PAC22".

_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.
_eval_slope_CMT.csv_ is a repetion of the set-up used for trainings_data.csv, but with CMT welding.
_eval_constant_CMT.csv_ uses a constant CTWD of 10 mm during CMT welding.
