DESCRIPTION
The SP Weldinq Gun - Continued
The swing arm is secured in the closed position by a pressure screw (12) and a pres-
sure spring (13). A, 50-foot control cable (14) extends from the base of the handle,
and has a plug for connection to the control.
A protective shield (15) is secured to the mounting bracket and includes the electrode
speed control (16). A four-inch diameter spool of welding electrode (17) is mounted on
the spool shaft supported by the shield. A plastic cover (18) is secured to the spool
shaft supported by the shield. A plastic cover" (18) Is secured to the spool shaft by
a knurled thumbscrew. The combination of protective shield and plastic cover complete-
ly enclose the welding wire spool and provide protection against spatter or other for-
eign matter. The plastic cover also enables the operator to see the quantity of weld-
ing wire remaining the spool. An adjustable spool brake (19) is secured to the
protective shield, and bears against the wire spool to prevent uncoiling of the weldlng
wire.
In operation, the welding electrode from the spool passes thru the rear guide bushing,
between the drive and idler roll, thru the front guide bushing, and thru the guide tube.
The wfre then passes thru the nozzle to the arc. Welding current is transmitted thru
the current cable to the gun barrel and to the guide bar, which in turn, transmits weld-
ing current to the welding wire. When the weld trigger is squeezed, the wlre drive
motor is energized to feed the welding wire to the arc and the gas valve opens to supply
shielding gas to the arc area.
NOTE :
Inching circuit not included in CV-2 Control.
Inch button will operate when this gun is
used with CVS-2 or CC-2 Control.
INSTALLATION
Immediately after opening the carton, make a careful examination of the contents to en-
sure that no damage has occurred during shipment. Do not discard any packing without
first accounting for all small parts such as guide tubes. If any shortage or damage is
discovered or suspected, promptly file a claim with the carrier and notify the nearest
Sales Office.
Gas Connections
Gas is supplied to the welding gun thru the gas hose which must be connected thru a
regulator and flowmeter to the shielding gas supply.
Location
The ideal location for this welding equipment is a clean, dry place where the tempera-
ture does not exceed 40C. (104F.). Under these conditions, the system can be expect-
ed to give excellent performance with a minimum of maintenance.
