TIG WELDING – INTRODUCTION cont’d

3. The flow of inert gas must be set to a value of 20-25

CFH. If you are using gas-lens type accessories, the gas
throughput may be reduced.

4. The diameter of the ceramic nozzle must be 4 to 6 times

the diameter of the electrode

5. Use D.I.N. 10 protective glasses for up to 75A, and D.I.N.

11 from 75 A up.
