FLEX FEED™ 74 HT

PRODUCT DESCRIPTION

GENERAL PHYSICAL DESCRIPTION
The Flex Feed 74 HT is a heavy duty industrial wire feeder. At
the heart of the feeder is the proven wire drive and motor, capa-
ble of feeding large diameter electrodes and pulling through long
conduits.
The feed plate may be located on either the left or right hand
side of the wire drive housing for easy integration into any work
center. The feed plate rotates easily to lessen strain on the gun.
Two wire reel stands are available for optimizing the feeder size
to the consumable package.
A new series of gun adapters has been created for improved reli-
ability and lower voltage drop.

GENERAL FUNCTIONAL DESCRIPTION

The base model Flex Feed™ 74 HT has knobs for wire feed
speed and remote voltage control. A large rocker switch on the
side of the feeder allows for activation of Cold Feed and Gas
Purge.
2-step/Trigger Interlock offers operator comfort when making
long welds.
Two wire feed speed ranges are available, dependent upon the
pinion gear installed in the wire drive.
The advanced user interface includes digital meters for the dis-
play of amperage and voltage while welding. The displays do
not show preset values. The user interface also has timers for
preflow, burnback and postflow.
The gouging option provides a means for connecting the gouging
torch to the feeder and a switch for activating the power source
output. High powered contactors inside the wire feeder isolate
the wire drive and the gouging circuit.
