CAUTION
‡
In using the welding power source for TIG welding, prepare a welding torch by the
customer.
‡ Contrary to the normal connection, the TIG welding requires connection of the welding
torch to the output terminal (base metal side). Also, connect the power cable for base
metal side to the output terminal (torch side).
‡ After five seconds have passed, the safety voltage (approx.15 V) is automatically
provided.
