12. Gas Pressure Indicator
Indicator used to show low, optimal and high gas pressure. Torch type, lead length, cutting mode and amperage should
all be set prior to setting the gas pressure. (90 - 125 PSI / 6.2 - 8.6 bar)
One of 7 segments will always be on when unit is on. The gas bottle will be illuminated and flash during a gas pressure
fault. Bottle will flash when pressure is below a minimum threshold. Bottle will be on continuously when acceptable.
Factory default: One, or two segments and gas bottle will be illuminated depending on the gas pressure level. The
green indicator in the middle indicates the recommended pressure for the process (Amps, torch type, lead length).
Different processes have different optimum pressures.
Yellow indicates above or below optimum pressure and red indicates unacceptable pressure for good cutting. Each
LED represents 5 psi. Two adjacent LEDs will represent a value in between the two or 2.5 lb. pressure change..
13. Gas Pressure Selector
Rotate the lower knob to set the gas pressure.
14. Torch Type Indicator
Used for selecting one of the three torch options and torch length for each. SLV will be automatically detected.
Factory default: On, SL60 which includes SL60QD™ (Quick Disconnect)
Press and release the lower knob without rotating it to step through selection of torch type.
NOTE!
If you have gone past the desired setting, you will need to continue to step
through all the other torch types and lengths to get back to return to it..
15. Lead Length Indicator
Used for selecting torch lead length for each torch type ranging between 20’ and 100’ leads.
Factory default: On, 20’ or 25'
Press and release the lower knob without rotating it to step through selection of torch type followed by lead length.
Up to 35’ Lead (10.7 m)
Above 35' to 50’ Lead (15.2 m)
Above 50' to 75’ Lead (22.9 m)
Above 75' to 100’ Lead (30.5 m)
NOTE!
If you have gone past the desired setting, you will need to continue to step
through all the other torch types and lengths to get back to return to it..
