this state when a weld trigger signal is received or when the user touches the “WELD” button. e
welder enters this state when the user touches the “NO WELD” button or after a welding and/or
charging sequence has occurred.
WELDING
Transition to this state happens from the WELD state when a trigger signal is received. is is
where all weld head operations, PLC signaling, and welding processes take place. Welder and user
interface settings may not be adjusted in this state. Transition from this state occurs automatically
when all current welding-related processes have finished.
COOLINGWELD
Many of the components inside the welding unit generate significant amounts of heat under
various operational conditions that, if not dissipated quickly, could damage critical components of
the welder. e welder is equipped with sensors that detect excess heat conditions and activate
heat dissipating fans to remove it. e welder is moved to this state when the heat sensors detect
excess heat to ensure that component damage is avoided. All functionality of the WELD state may
be performed in this state.
COOLINGNO WELD
Many of the components inside the welding unit generate significant amounts of heat under
various operational conditions that, if not dissipated quickly, could damage critical components of
the welder. e welder is equipped with sensors that detect excess heat conditions and activate
heat dissipating fans to remove it. e welder is moved to this state when the heat sensors detect
critical amounts of heat. Welding processes are suspended to ensure that component damage is
avoided. All functionality of the NO WELD state may be performed in this state.
ALARM/NOTIFICATIONWELD
is state is used when certain functions of the welder are enabled to notify the user of specified
conditions. When a fault or error condition is detected, a warning message is displayed until the
message is suspended. Welding processes continue normally unless the user intervenes.
ALARM/NOTIFICATIONNO WELD
is state is used when certain functions of the welder are enabled to notify the user of specified
conditions. When a fault or error condition is detected, all welding procedures are aborted and
a warning message is displayed until the message is suspended. Welding processes will not
