The duty cycle limits for the Nelweld N1500i can be seen in the Stud
Weld Rate table below. If the duty cycle is exceeded, and a weld is att-
empted, a “Wait” prompt will be displayed. “Wait” will disappear
when the unit is ready for another weld. If the unit reaches an abnor-
mally high temperature, a failsafe thermal sensor will protect the unit
and display E011. The unit will resume operation once the temperature
has returned to safe operating range.
