<p>Welding simulator The welding simulator (!) comprises a flat inclined base (2) of an insulator material mounted on a horizontal flat mounting surface consisting of a table top (3) and having a high end (5) inclined at an angle with respect to the flat mounting surface and a low end (6) resting against the flat mounting surface. The flat inclined base further has a plurality of permanent magnets (10) arranged in a row extending from the high end to the low end of the inclined base. A flat dummy work piece (12) of conductor material is located over the row of permanent magnets. A reference rod (13) is disposed at a height above the row of permanent magnets. A welding electrode holder (18) with a welding electrode (19) which is linearly movably engaged around the reference rod describing a clearance with the reference rod. The welding electrode has a light emitting diode (23) attached thereto and connected to a DC source (24) of 12-14 Volts. The welding electrode is connected across the +ive terminal of the DC source and forms a normally open circuit with a first buzzer (Bl) and the work piece connected across the -ive terminal of the DC source. The welding simulator also comprises a welding electrode speed indicating means (PS1, PS2).</p> |
