Attach the Regulator and Flowmeter to a cylinder of pure argon by
threading nut on regulator-flowmeter to matching threads on cylinder.
Tighten nut to prevent gas leaks. Gas cylinder is not part of weld-
Attach nut on gas hose from welding gun to the matching threads on the
outlet side of regulator-flowmeter and tighten to prevent gas leaks.
Insert plug on the end of the current cable from welding gun into the
matching receptacle on the control monitor. This plug is keyed and
must be rotated to the proper position before inserting. After inserting
plug, turn plug 1/4 turn clockwise to lock in place.
Insert plug on end of control cable from welding gun in matching re-
ceptacle on the control monitor. This plug is also keyed and must be
rotated to the proper position before inserting. After the plug is
lined up properly with receptacle, gently work plug into socket and
tighten retaining ring.
Attach current cable from control monitor to the positive (+) output
terminal of the welding power supply. This cable includes a large
terminal for connection to the positive (+) output terminal. Since
this welding set may be used with various types of welding power supplies,
some adaption to make this connection may be required. However, a tight
connection is required. On welding power supplies which include a polarity
switch, this cable should be attached to the terminal marked electrode and
the polarity switch should be placed in the "Reverse Polarity" position.
CAUTION: Operate the welding set with the welding power source set on
"Reverse Polarity" only. If set on "Straight Polarity", the flow of current
will reverse, the wire feed motor will run in reverse, pulling the wire
back into the gun, and a very severe "burn back" will result.
Attach one end of ground cable and the ground cord from the control monitor
to the negative terminal of the welding power supply. This must be a tight
connection. On welding power supplies with a polarity switch, these leads
are connected to the "Work" terminal. Connections should be tight.
Connect the other end of the ground cable to the workpiece or material to
be welded. This must be a tight connection.
Connect the line cord to a 110 to 125 volt AC or DC supply. This cord
is equipped with a standard 3-prong plug. For connection to a 2-prong
supply, an adaptor is provided. Where used, the screw on the side of
the adaptor should be connected to the frame of the welding machine with
a short piece of wire.
