2. Slowly open the cylinder valve.
3. Set the flow rate on the regulator to approximately
15 to 25 CFH.
4. Close the cylinder valve and pay attention to the needle
indicator on the regulator's pressure gauge. If the needle
drops away towards zero there is a gas leak.
Sometimes a gas leak can be slow and to identify. Leave
the gas pressure in the regulator and line for an extended
time period. Perform the test as above, but reduce the flow
rate to 16-21 CFH. Close the cylinder valve and check after a
minimum of 15 minutes.
5. After confirming there is a loss of gas, check all connectors
and clamps for leakage by brushing or spraying with soapy
water. Bubbles will appear at the leakage point.
6. Tighten clamps or fittings to eliminate gas leakage. Replace
the clamps and fittings if this fails to solve the problem.
OPERATION
THERMAL OVERLOAD PROTECTION
Constantly exceeding the duty cycle can damage the cutting unit.
An internal thermal protector will open when the duty cycle is
exceeded, shutting OFF all cutting unit functions except the
cooling fan. Leave the cutting unit turned ON with the fan
running. The thermal protector will automatically reset and the
cutting unit will function normally again once it has cooled.
Wait at least another 10 minutes after the thermal protector
opens before resuming cutting. Starting before this additional
time may result in a shortened duty cycle
OVER-VOLTAGE
This equipment has an automatic voltage compensation
function, which enables the unit to maintain the voltage within
