Weldtron UI and Weldtron UI-1 idle control modules.
Upgrade or modify any machine to idle automatically.
No external sensors required. Totally self-contained with current sensors.
Have a good working R-57 Vacuum idler control but don't want to change the whole
system over to a new complete electrical system. You're in luck. The
Weldtron-UI can now be used to upgrade existing R-57 vacuum idler controls
without the need to replace ANY electrical or mechanical parts.
