Ensure Emergency Stop Switch is working
WARNING: THIS MUST BE DONE PRIOR TO OPERATING WELDER
In order to verify that the emergency stop switch is working properly, plug in the included
emergency stop push button into the 3DIN connector on the back panel. Plug the welder into AC
power. Turn the unit on by pressing the power LED button on front panel. Once the unit has come
to the interface users will see “WELD OFF” on a tab at the top left of the screen. Press that button
to place the unit into a welding state. The button should now indicate “WELD ON”. At this point
engage the emergency stop button. After this the welder should automatically go into a “WELD
OFF” state. The button on the top left of the screen will change from “WELD ON” to “WELD OFF”. If
this happens, then the emergency stop is working properly and users can begin welding with the
unit. If this doesn’t happen please contact customer support.
