Abstract

PURPOSE: To eliminate the variance in the output voltage of a coil and know an accurate current value by interposing and fixing a rectangular conducting piece wound with the coil on the outside circumference in close contact therewith to part of the secondary circuit of a welding machine.
CONSTITUTION: When a coil for measuring welding current is used for a multispot welding machine, a rectangular conducting piece 6 wound with a coil 5 in close contact therewith is connected to one of the output terminals T1, T2 of a welding transformer T, and cables 7, 8 are connected to this piece 6 and the other output terminal T2 and are respectively connected to the holders 9, 10 of welding guns G1, G2. This case is series spot welding, wherein it turns out that spot welding of two points is accomplished with one welding circuit by using a back bar. The above eliminates the variance in the output voltage of the coil, and facilitates setting of welding conditions. Since the device is fixed to the secondary side of the welding machine, there is no moving in the and of a toroidal coil as on the prior art, and the failure of the coil itself is prevented.
