equipment's components. Please ensure your primary power supply is correct
(see Specifications).
The overvoltage LED (L) will switch on when there is an overvoltage.
POWER REQUIREMENTS
The power cord supplied with this welding unit is designed to handle the
maximum power required (see Specifications). Refer to the welding unit's data
plate and ensure the power supply can meet those requirements.
CHECK FOR GAS LEAKAGE
Check for gas leakage each time the welding unit is set-up for TIG welding and
at regular intervals.
1.
Connect the regulator and gas hose assembly and then tighten all
connectors and clamps.
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 difficult to identify. Leave the gas
pressure in the regulator and line for an extended time. Perform the test as
above, but reduce the flow rate. 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.
SET-UP FOR DC TIG OR DC PULSE TIG
1.
Connect the TIG torch to the power socket.
a.
DC Electrode Positive (DCEP) – Connect the TIG torch to the positive
power socket (E).
b.
DC Electrode Negative (DCEN) – Connect the TIG torch to the negative
power socket (G).
