SECTION 4
Measure the flow rates using a new 200 amp nozzle (0558003798), a new electrode and a new heat shield. Make
sure that all parts are properly installed and that the torch o-ring (0558003721) is in good condition and not leaking.
Measure the flows individually if possible, if not measure the total.
Gas flow rates less than those above indicate a restriction or a leak in the gas plumbing of the torch or power source.
4.9 TROUBLESHOOTING CUT QUALITY
Data taken with Swirl Baffle (0558003583) and Shield Cup (0558003582).
65 Amp data uses standard Heat Shield (0558003714) or Close Proximity Heat Shield
(0558003715) in place of Shield Cup (0558003582) and uses a 50 Amp Nozzle (0558003716).

* It is possible to go much faster, but 50 ipm (1270 mm/m) gives the best quality cut.
To ensure optimum cutting performance and
aid in troubleshooting any cut quality prob-
lems, please refer to the following cutting
parameters charts.
