2.2.5 Wire Grip Mechanism and Drive Roll Carrier
The wire grip mechanism is a piston that forces the drive roll carrier to
grip and start feeding the wire. The piston is actuated by the wire feed
valve on the handle. The turbine, countershaft and lower drive roll turn
continuously whenever the gas head valve is in the run position. The
wire grip mechanism forces the upper drive roll gear to engage the
lower gear and grip the wire.
The adjustment screw at the back of the
wire grip mechanism is factory-set and should not be changed.
A man-
ual wire grip mechanism is optionally available. (See “14EWGM Man-
ual Wire Grip Mechanism” on page 22.)
2.2.6 Handle and Wire Feed Control
The
WIRE FEED ON-OFF
control is an air valve that actuates the
automatic wire grip mechanism. If the manual wire grip mechanism is
installed, there is no wire feed control on the handle.
2.2.7 Rear Wire Guide and Snubber
The snubber allows the wire only to feed forward and prevents the
wire from being pulled out the back of the gun. The rear wire guide and
snubber can be changed for different size wires. (See “Hardware
Selection” on page 26.) A strain relief wire guide is also provided
which should be used with brittle wires, such as Metco 405. The strain
relief maintains a radius in the wire to help prevent the wire from
breaking as it enters the gun.
DANGER
Always make sure the
snubber is locked. If the
wire is pulled out of the
rear nozzle while the
gun is lit, the fuel gas
may flash back through
the rear wire guide.
Also, the wire end can
be extremely sharp. If
the wire comes out of
the gun it can cause
personal injury.
