11.1 Welding conditions table
11.1.1 TIG welding conditions table (Reference)
The list of TIG welding conditions shown in this
chapter is a reference value as a guideline for
standard welding conditions.
In actual welding operations, work out an appropri
-
ate condition in consideration of the shape of sub
-
stances to be welded, a welding position, etc.
In case arc is not stable in the low current range,
refer to section “Troubleshooting.”
