At initial set up and at regular intervals we recommend to check for gas leakage.
Recommended procedure is as follows:
1. Connect the regulator and gas hose assembly and Tighten all connectors and clamps.
2. Slowly open the cylinder valve.
3. Set the flow rate on the regulator to approximately 8-10 l/min.
4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure
gauge on the regulator, if the needle drops away towards zero there is a gas leak.
Sometimes a gas leak can be slow and to identify it will require leaving the gas pressure in the
regulator and line for an extended time period. In this situation it is recommended to open the
cylinder valve, set the flow rate to 8-10 l/min, close the cylinder valve and check after a
minimum of 15 minutes.
5. If there is a gas loss then 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.
ATTENTION! - CHECK FOR GAS LEAKAGE

8: Arc dif cult to start or will not start DC welding
Possible Reason
Suggested Remedy
Incorrect machine set up
Check machine set up is correct
No gas, incorrect gas ow
Check the gas is connected and cylinder valve open, check hoses, gas valve and torch
are not restricted. Set the gas ow between 10 - 15 l/min ow rate
Tungsten is contaminated
Remove 10mm of contaminated tungsten and re grind the tungsten
Incorrect tungsten size and or tung-
sten being used
Check and change the size and or the tungsten if required
Loose connection
Check all connectors and tighten
Earth clamp not connected to work
Connect the earth clamp directly to the work piece wherever possible
