DEFECTS

SOLUTIONS

Destruction of the nozzle

- The destruction of a nozzle can be caused by :

- a power increase which is too quick : increase the power run-up
time-delay,

- contact with the part due to a metal projection during arcing in
middle of sheet metal: raise the torch at time of transfer,

- direct contact with the part,

- a lack of cutting gas : check the flowrate or the cutting gas circuit,

- intensity too great for the diameter of the nozzle used: see scale,

- poor cooling : check the flow on the return circuit and the
temperature of the cooling circuit.

Destruction or rapid wear of flat electrodes - Check the condition of the gas barrel.

- Increase the flowrate of the cutting gas.

- Check the cooling circuit.

- Dipping tube in poor condition (water flowrate condition).
