PURPOSE:To prevent bridging of a brazing filler metal between brazing parts and the other parts adjacent thereto by providing a shielding plate freely attachably and detachably to and from a table thereby shielding the brazing parts from the other parts. CONSTITUTION:The flame of a torch 20 is applied to the wire parts to be brazed and the preceding end of a brazing filler metal 30 is projected to the brazing parts. When a torch head 17 descends, a shielding plate 41c provided to a holder 41b projects as well in the direction of an armature assemblage 11 and the preceding end parts thereof sandwich the preceding end of the armature in the brazing parts from both sides thereby shielding the armature in the brazing parts against the other armature adjacent thereto. In this stage a sequencer 36 applies a required quantity necessary for brazing as a signal S1 to a pulse generator 33 and applies a periodic changing signal S2 to a period changer 35. |
