5.2 - MANUAL GAS TUNGSTEN ARC WELDING (TIG)
1. Connect the welding accessories carefully in order to avoid power
losses. Carefully comply with safety rules.
2. Connect the welding cables to the output terminals of the unit for the
selected polarity.
3. Attention: insert the male connector with the key lining up with
the keyway and rotate approximately ¼ turn clockwise. Do not
over tighten.

Put the tungsten electrode in contact with the piece; a low current
passes through the electrode.
As the torch is raised the electric arc is set up and the welding
current rises to the pre-set value.

approved respirator. Consider using tungsten containing cerium,
lanthanum, rare earths instead of thorium. Grinding dust from
thorium electrodes contains low-level radioactive material. Properly
dispose of grinder dust in a environmentally safe way. Wear proper
face, hands and body protection.
The tip of the electrode is sharpened into a cone so that the arc will be
stable and the energy concentrated on the area to be welded.
The length of the sharpened section depends on the electrode diameter:
