Handle gas bottle with care. There is a risk for injury if gas bottle or bottle valve is damaged!
NOTE!
Use inert gases such as argon, helium or argon-helium mixture as shield gas for TIG welding.
Make sure that the gas flow regulator is suitable for the gas type used. The flow rate is set
according to the welding current, joint form and the size of the electrode. A suitable flow rate
is normally 8 – 10 l/min. If the gas flow is not suitable the welded joint will be porous. Spark
ignition becomes more difficult if the gas flow is too high. Contact your local Kemppi dealer
for choosing gas and equipment.
