If converter cooling is required, use the following steps:
A 0.06 in (1.5 mm) orifice at 50 psi (345 kPa) will result in a reading of 80 ft

(2.26 m

)
per hour. This should be sufficient to cool most operations requiring a cooling air stream.
In continuous welding operations, or applications with longer duty cycles, it may be
necessary to cool the horn as well as the converter. Horns may require cooling because of
the heat transfer from contacting the work piece.

Step
Action
1
Start with a 50 psi (345 kPa) air source or higher from a 0.06 in (1.5 mm) I.D.
orifice
2
Perform a run of welding operations.
3
Immediately after completing the welding run, check the converter
temperature.
4
If the converter is still too hot, increase the diameter of the orifice in small
increments until the temperature falls within the ranges in the chart.
