Precautions for the CNC Table
Warning: During weld head operation/program RUN it is important not to place hands or body extremities
directly below the Gas Cone or inside the travel envelope of the XYZ Table. e weld head makes sudden
movements and could pinch/smash/impact hands or other body extremities as it travels.
Caution: Always check the Z height settings prior to initiating a program. If the Z depth is set too low, the
unit can enter an Over-Force state that could damage the workpiece or weld head components.
Warning: Always disconnect the AC power cord before removing any cover panels. ere are live AC
connections inside the unit that could be an electrocution risk if the unit is plugged in. Note: removal of the
covers could void the warranty.
Caution: e electrode is often used in a sharpened state for weld applications. When removing the brass
Gas Cone for electrode maintenance, be aware that the electrode will be exposed and is a sharp object
that can puncture the flesh.
Warning: Keep fingers and clothing away from the cable chain while the unit is running.
Caution: During weld discharge, a bright flash can sometimes escape from beneath the tip of the brass
