MANUAL ELECTRIC-ARC WELDING OPERATOR TRAINING APPARATUS Russian patent published in 2006 - IPC B23K9/00 G09B19/24 

FIELD: didactic devices for learning primary procedures and skills of manual electric arc drill.

SUBSTANCE: training apparatus includes housing, welded parts simulator, electrode mounted in electrode holder and electronic voltage conversion circuit. Said circuit is arranged inside housing and it represents voltage converter whose outlet is connected with electrode and with welded parts simulator. Said simulator is in the form of flexible thin metallic substrate to which paper sheet is secured by means of magnet. Simulator is mounted with possibility of changing inclination angle for simulating different types of welded seams. Flexible thin metallic substrate may have flat or curvilinear surface. It shortens time period of learning and improves its visualization due to using feedback circuit and due to possibility for writing operator actions on paper sheet.

EFFECT: improved design, enhanced efficiency of learning.
