In addition, the application can also quickly clamp and position the parts that need to be limited and fixed by utilizing the setting of the limit rod, knob and pressure plate. However, when fixing the parts, the application can only fix the parts on the base, and the parts cannot adjust the welding angle and welding position during welding. Therefore, when welding some parts, since the welding surfaces of the two parts have a certain circumference, the parts cannot be welded after being fixed by the application, and then part of the welding surfaces of the two parts cannot be welded. Therefore, after welding a part of the position, the limit rod needs to be adjusted, so that the part is removed and adjusted to the position or angle and then fixed again, which reduces the welding efficiency of the parts.
