An observation through groove is formed in the position, corresponding to the handle and the material conveying pipe, of the handle; the observation through groove is communicated with the material conveying channel and the outside, so that an operator can directly observe the solder allowance in the material conveying channel from the outside, and the solder allowance can be timely supplemented when the solder allowance is insufficient.

An observation window is hermetically arranged in the observation through groove; prevent that the steam in the discharging channel from leading to the groove through defeated material passageway and observation and discharging from the side, if not set up the observation window, follow the easy eyeball of burning people that leads to the groove and emit from observing when observing the logical groove and observing the solder surplus from operating personnel.

The observation window is made of antifogging glass; if use ordinary glass, during the use of winter, because outside is cold, the inner wall is because bonding tool temperature is higher, and the great extremely easy fog that produces of difference in temperature between the two to influence operating personnel and observe, antifog glass can prevent effectively that the fog from producing, guarantees that operating personnel can in time look over to inside through the observation window.

Compared with the prior art, the utility model discloses when using different types of solder, because the partial easy adhesion is on the discharging channel inner wall of bonding tool behind the solder wire melting, when the solder of another kind is discharged from discharging channel, two kinds of solders mix easily, the utility model discloses a change the bonding tool in order to prevent the mixture between two kinds of solders, only have a solder to discharge when guaranteeing to weld and be used for the welding.
