摘要：PROBLEM TO BE SOLVED: To provide a C-shaped welding machine having a gun bracket forming a secondary conductor of the welding current without requiring any components such as a shunt and a bus bar for conduction to fixed arms, capable of reducing the weight and the cost and easily adjusting the space between a worker and the welding machine, and applicable to fixed arms of different dimensions. SOLUTION: At least three fixed arm fitting holes 9 in the transverse direction and in a plurality of stages in the longitudinal direction are formed in a part of a gun bracket 2 with a fixed arm 5 being held thereby. The fixed arm is held by a fastening tool 7 passed through at least two fitting holes selected from the fitting holes. One secondary current terminal 11 from a welding transformer 6 is connected to the gun bracket, and a space between the welding transformer and the fixed arm forms a conduction path of the welding current via the gun bracket.
