By combining a positioner with a welding power source and a torch stand, a welder can perform semiautomatic welding that is productive and ergonomically friendly. The positioner holds the part and maneuvers it under a stationary torch. This torch can be fitted with a weaving device to allow oscillation to fill large gaps or V-grooves. Consistent speed and torch position improve the quality of the weld with greater repeatability. By using a communication cable between the integrated positioner and a welding power supply, the operator only needs to signal a start through a foot pedal or a start button, and the welding cycle will continue until the signal is automatically sent that it has completed. This method, typically used on a circumferential weld, can incorporate dwell times to create a puddle and fill the crater. The completed part is removed and another is started.

How a weldment is attached to a positioning device is as important as the positioner itself, because this is the point where separation would naturally occur. Production fixtures are designed for a specific application performed repeatedly. This type of fixture is mounted permanently to the positioner, and its specific shape allows for easy part alignment.
Round parts often are attached by a three-jaw chuck. The part must not pull away from the jaws when the part extends from the table. Also, the part may expand or contract from the heating and cooling that occur during and after the welding process, which can change the grip that the chuck has on the workpiece.
Fixtures and chucks add weight and distance from the faceplate, which needs to be considered when sizing the positioning device. While the weight of a weldment applies torque to the device, the distance that weight is applied multiplies the torque by the increase in distance. For example, a 50-lb. weldment that is 3 inches away from the face of the positioning table creates 12.5 ft.-lbs. of torque in the vertical position. If the distance is increased to 6 in., the torque increases to 25 ft.-lbs. at the mounting surface. The increased torque may require a larger-capacity machine.
