Title: Arc welding power unit
Inventor: MOTOMIYA AKINORI
IPC: B23K9/10
Filed: 1990-06-27
Abstract: PURPOSE:To obtain good arc start performance and to shorten welding work time by changing the feed quantity of a consumable electrode from the welding start up to the arc generation in a state with the welding wire tip cooled and in a state with this red-hot. CONSTITUTION:The temperature of the welding wire 8 tip is monitored at the time from welding completion and when the welding wire tip is in a cooled state, the feed quantity of the welding wire tip is made slower than the welding wire feed rate at the time of stationary welding. When the welding wire tip is in a red-hot state, the welding wire feed rate is made faster than when the welding wire tip is in a cooled state. As a result, the good arc start performance is obtained in the same way when the welding wire tip is in a cooled state and when this is in a red-hot state. Consequently, the synthetic welding work time can be shortened and the welding workability can be improved.
