<p>Contact blobs are formed at the ends of lead wires for electric, preferably semiconductor, components in a process using a direct current light arc, whose current has been stabilised to a desired current strength, while the duration of the light arc has been limited to a certain time period. The equipment contains a high voltage storage capacitor (2) whose discharge circuit incorporates the arc spark gap (b) between the lead wire (3) and a counter-electrode (7). The capacitor discharge circuit contains an electron tube in grid-base connection and a current stabiliser, both in line with the arc spark gap.</p> |
