the height of the height adjusting stud (135) is adjusted through the relative rotation of the lower nut (136) and the height adjusting stud (135) so as to ensure that the initial height position of the alloy welding wire (120) is positioned above the tooth crest of the band saw blade (130).
10. The alloy wire automatic feed welding mechanism of claim 9, wherein: a limiting connecting block (127) is fixedly arranged on the front side part of the welding handle (105), a first welding handle limiting screw (139) is in threaded connection with the limiting connecting block (127), and the position of the welding handle (105) is adjusted by rotating the first welding handle limiting screw (139) so as to control the anode welding claw (108) to rotate to the lowest position;
the side part of the welding handle support (106) is in threaded connection with a second welding handle limiting screw (140) which is positioned below the rear side part of the welding handle (105) so as to control the highest position to which the anode welding claw (108) rotates.
