[45] As shown in FIG. 1 through FIG. 3, in the welding machine of pincette type 100 of the present invention, minute accessory patterns can be formed in three dimensions through a resistance welding, so that it can create a higher value-added business. [46] The welding machine 100 of pincette type of the present invention includes three parts, that is, electrode plates 10 connected to an electric power, power lines 20 for supplying the power to the electrode plates 10, and a pressure member for forcibly pressurizing the electrode plates 10. [47] A pair of the electrode plates 10 are mutually arranged in a predetermined distance and elastically fixed to a supporting member in order to be elastically returned during the applying of a predetermined pressure. [48] Here, the supporting member includes a pair of disks 50 supporting the electrode plates 10 upward and downward and fixed to each other through a bolt 51 and a nut 52. [49] Accordingly, the electrode plates 10 can be elastically returned through the supporting member during the applying of a predetermined pressure. [50] Also, the power lines 20 are electrically connected to one end of each electrode plate 10 in order to supply the power to the electrode plates 10 and the pressure member is connected to another end of each electrode plate 10 in order to forcibly pressurize the electrode plates 10 by means of the grip power. [51] The pressure member is a pair of metal pipe 30 of a "U" shape having an insulating rubber 31 for preventing an electric shock and a burn.

[52] Also, a welding tip 11 for welding the parent materials (metals) of the minute accessories is coupled to each one end of the pressure member. Here, the welding tip 11 is gradually decreased downward in area so as to easily clamp the minute accessories. [53] Also, the pressure member of a metal material is thermally increased through the supply of the power by means of the power lines 20, so that a high heat is generated in the pressure member. Here, the cooling means for cooling the heat is connected to the pressure member. [54] The cooling means includes a rubber hose 41 connected to the metal pipe of the pressure member and a pump 43 received in a water tank 42 for forcibly supplying the water to the pressure member through the rubber hose 41.

[60] Thereafter, a solder is melted in the contact surface between the parent materials thermally increased through the electric resistance to be welded. [61] Here, since the pump 43 is continually operated, the cooling water is forcibly circulated inside the meal pipe 30 of the pressure member through the rubber hose 41, so that the insulating rubber 31 for covering the pressure member is not melted and it can be used for many hours by preventing the thermal increasing of the pressure member. [62] FIG. 4 is a flow chart illustrating an accessory cubic formation method using a welding machine of pincette type according to one embodiment of the present invention.
