Preparation for Welding

Connect the electrical power 115 volt 60 single phase line. Connect the shop air supply to the inlet at the filter. Connect the ground cable from the power supply to the ground lug. Refer to the appropriate manual supplied by the welding apparatus manufacturer for instructions on the hook-up of the electrode cable, inert gas, water supply, and water drain

Operation

Set the carriage speed for the welding parameters and the welding process you have chosen, as recommended by the manufacturer of the welding apparatus.

Open the latch at the end of the mandrel.
Slide the piece parts over the insert so that the edges to be welded are at the top.
Close the latch.
Telescope down the extension arms of the piece part centering devices and rotate the centering device blades down until they contact the center of the groove. Be sure that the backside of the blade is in alignment with the center of the groove.
Align the left and edge (back side) of the piece part to be welded over the center of the insert groove placing the edge of the piece part against the rear surface of the blade and pushing the “left” button on the pendant control to close the rear bank of fingers. Rotate the centering device blades up and telescope up the extension arms of the centering devices.
Align the right-hand edge (front side) of the piece part as close as possible to the piece part which is clamped in the seamer and push the “right” button on the pendant control. The fingers will close and remain clamped. In addition, the fingers on this side will move the piece- part in towards the previously clamped edge. This will effectively close the gap between the edges to be welded, provided they were accurately sheared.
Set the welding parameter on the welding process you have selected. Refer to the appropriate manual supplied by the welding apparatus manufacturer.
On completion of welding, push both buttons on the pendant control to raise the fingers; open the latch, and remove the part.
