Recently, there has been much research and development into coated metal enclosures that are constructed watertightly and airtight by seam welding (resistance welding) both rising parts (joints) of coated stainless steel to the inner and outer surfaces of structures. There is. In order to seam weld the long linear rising parts, spot welding is mainly used to temporarily fix the rising parts as a preliminary step. Furthermore, when joints formed by seam welding are seam welded together as a T-shaped joint as shown in Figure 6, especially the A and B portions of the T-shaped joint (Figure 7). When the plate thickness changes suddenly (in fact, the number of plates changes) and a step occurs, as in (see), the disc electrode of the seam welder cannot follow the shape of the step, It may become impossible to weld the stepped portion, and a gap may be formed, and spot welding is also used to repair incomplete seam welding. Although the manual spot welding machine is manufactured to be relatively compact for portability, it actually weighs about 10 kg to about 10-odd kg.

労力を要し、作業能率が低減する欠点があつた。 Therefore, while supporting the manual spot welding machine, you can place it at the desired position of the joint (rising part).
Setting the tip of the electrode tip requires a long period of time, is extremely difficult to position, requires considerable labor, and has the disadvantage of reducing work efficiency.

Furthermore, since the tip of the electrode tip may be set at a desired position while supporting the welding part, it may become difficult to carry out proper spot welding work. As described above, although it is portable, it is extremely difficult to easily operate manual spot welding machines.

ような最小限の支持力のみである。 To explain these effects in detail, first, welding machine main body 1 in the intermediate position of manual spot welding machine is
By supporting the weight with each groove wheel 6, the force to support the entire weight of the manual spot welding machine A is almost unnecessary, and the power to support the running stability of the manual spot welding machine A is slightly reduced. Because of this, there is only a minimum amount of support required to support both sides.

がある。 This can be done in particular by reducing the weight of the manual spot welding machine A to the welding machine main body 1 in the intermediate position.
By supporting the welding machine body 1 with the groove wheel 6, the electrode tips 4, 4 on the tip side can be easily swung on the welding machine main body 1 above and below the operating section on the base side without considering the weight of the welding machine body 1. Moreover, since it does not require any weight, it has the great advantage of being extremely simple, quick, and accurate even when making delicate level adjustments to a desired position.
