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 21-30cfh.

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 21-30cfh, 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.

Important:

We strongly recommend that you check for gas leakage prior to operation of

your machine. We recommend that you close the cylinder valve when the machine is not

in use. Jasic Technologies America, authorized representatives or agents of

Jasic Technologies will not be liable or responsible for the loss of any gas.

ATTENTION! - CHECK FOR GAS LEAKS

8: Arc difficult 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 flow

Check the gas is connected and cylinder valve open, check hoses, gas valve and torch

are not restricted. Set the gas flow between 10 - 15 l/min flow 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
