.
N.B.
• Turn off the switch of the switch box when connection cable.
• Provide a switch box for every welder and use a specified fuse.
• Power supply cable should be14 mm2 or more insectional area if its length is more than 10m.
• If an engine generator is used, it should be provided with an inverter of capacity from three to five times of the
of the welder with compensating winding for thyristor equipment.

4.3 REQUIRED EQUIPMENTS AND MATERIALS

Prepare the following equipment and materials for welding.
Torch for TIG welding(YT-30TSW2HAF)
Welding argon gas
Argon gas adjustor (YX-25AJ1)
Base metal side cable [Stick welding]

4.4 SELECTION OF TUNGSTEN ELECTRODES

Use the following table as reference for tungsten electrodes.
EIectrode rod (dia.)
(mmφ ）
Welding current (A)
(DC welding)
Welding current (A)
(AC welding)
Tungsten electrode ... ... ... YWTH (2% thoriated tungsten)
Use welding argon gas for TIG welding shield gas.
Impurities such as oxygen, moisture or nitrogen mixing into argon gas can deteriorate shieldability and lower
the quality of welding.
