CWE-5

The CWE-5 Circle Welding Machine with Remote Control has a digital readout for rotation speed. It also has controls for: wire feed speed, cold inch/purge, pre-flow and post-flow, burn back and wire feeder forward and reverse. Overlap is also adjustable. 

This Circle Welder’s control has both manual and automatic settings. In the manual setting, you can check all your controls and travel speed to make sure the machine is functioning properly. In the automatic setting, with one push of a button, the unit will start the weld process, weld completely around the workpiece, overlap the end of the weld, turn the weld off and return to the start position. It is ready for the next weld.
