Note
About shield gas
• Use the high-purity welding argon gas JISK1105 (99.9% or more in purity) as a TIG welding shield gas.
• Incorporation of impurities, such as oxygen, moisture, nitrogen, etc., into the argon gas may deteriorate the shield
performance and eventually reduce the welding quality.

<To increase the maximum gas flow-rate>
• The factory-set inside diameter of “gas outlet” joint is 1.0mm, and the maximum flow-rate is set to 20L/min.
• To increase the maximum flow rate, remove the setscrew

inside the “gas outlet” joint.
Eventually, the maximum flow rate is set to 45L/min. However, the gas regulator shall also be replaced with that pre
