Abstract
A system for conserving a consumable component of a plasma torch is disclosed. The system includes a controller of a plasma torch that is connected to a power source. The controller is configured to, during a single trigger actuation, delay generation of an arc after a prior arc collapses. Such a control allows the consumable components of the plasma torch to cool prior to subsequent operation.
Claims20
A welding-type system comprising:
- a plasma torch controlled by a trigger and constructed to generate an arc;
- an air supply connected to deliver an air flow to the plasma torch;
- and
- a controller configured to control the air supply, monitor actuation of the trigger, and continuously monitor for arc outage, and if arc outage is detected while the trigger is actuated, cause (1) continued air flow through the plasma torch for a predetermined period and (2) then regenerate a pilot arc in the plasma torch.
1 more element
A plasma cutting system comprising:
- a power source constructed to generate a plasma cutting power;
- a plasma torch actuated by a trigger and connected to the power source;
- and
- a controller configured to control the plasma torch to generate a first arc upon actuation of the trigger and generate a second arc after extinction of the first arc when the trigger remains actuated but only after an insert of an electrode of the plasma torch cools to solidify a portion of the insert that liquefies during operation.
1 more element
A controller of a plasma torch system configured to:
- monitor a condition of an arc of a plasma torch;
- and
- if the arc collapses and a trigger of the plasma torch system remains activated, initiate a delay prior to automatic generation of a subsequent arc.
