OPERATION

REAR CONTROL PANEL (FIGURE B.1)
• I1: Off/On switch turns on the electric power to
the welder. It has two positions, "O" off, and
"I" on.
------------------------------------------------------------
* With "l1" in the "I" (ON) position, the welding
machine is operational and there is voltage between
the positive (+) and negative (-) Terminals in stick
welding. In TIG, the welding process needs a trigger
closure command at the remote control connec-
tion.(Usually via an Arc Start Switch or Foot Amptrol)
* The welder is connected to the supply even if the
“l1” (Power Switch) is in the "O" (Off) position, and
therefore there are electrically live parts inside the
power source. Carefully follow the instructions given
in this manual.
