A device for training, evaluating and providing practice for welders and particularly welders and welder students that use MIG, TIG and welding devices that employ movable consumable welding rods. The device includes a video monitor having a cathode ray tube, the face of which has visual displays thereon, including displays from which simulated welding parameters can be entered and displays which simulate different welding joints with a welding target to be followed by the operator while holding the selected welding tool. The present device uses a microprocessor and related electronic devices programmed to generate the displays and to control the various machine operations. The device also includes a unique way to produce the various control responses necessary to the operation including optical and electromagnetic responses.
