74 MPa Plus See literature WFM/30.0 UK
Adds features for weld control and programs, plus push-pull aluminium capabilities.
Optimized with Invision
™
MPa or XMT
®
MPa power sources.
74S and 74D See literature WFM/30.0 UK
Standard, simple feeders for most heavy-industrial applications, with the 74D providing
increased accuracy and control of the most common weld parameters.
Adjustable run-in control for improved arc starts.
Dual schedule control allows the operator to switch
between two preconfigured welding parameters
without readjusting the machine, saving time and
enhancing quality.
Trigger schedule select saves time when switching
between two weld settings by simply tapping gun trigger.
Trigger program select provides the ability to access
any of the four active programs.
Sequence control gives the operator the ability to
adjust all of the welding parameters: preflow, run-in,
weld time, crater, burnback and postflow.
Locks and limits for restricting or limiting operator
adjust ments, such as voltage and wire feed speed
parameters.
Four weld program memories allow operators to
recall up to four previously used processes and their
weld settings.
Accu-Mate
™
properly seats the MIG gun power pin for
best feeding performance.
Push-pull capability provides consistent, versatile
and dependable aluminium wire feeding over
greater distances.
Recommended
aluminium solution.
Dedicated XR Plus guns
(gooseneck and pistol grip)
work with MPa Plus feeders
to coordinate wire feed speed of
the gun and the feeder. This provides
optimized aluminium feeding and welding performance.
See chart below for gun models and stock numbers.
Additional features when used with
Invision MPa or XMT MPa power sources
Synergic pulsed MIG. As wire speed increases/decreases,
pulse parameters also increase/decrease to match the
right amount of power needed, eliminating the need to
make additional adjustments.
Profile Pulse
™
provides
TIG appearance with MIG
simplicity and productivity.
Achieve “stacked dimes”
without gun manipulation. Profile Pulse frequency
can be changed to increase or decrease the spacing
between the ripple pattern to achieve the desired
weld appearance.
Digital meters (74D models only) ensure accuracy
when presetting and reading actual voltage, amperage
and wire feed speed.
Remote voltage control (74D models only) allows you
to set both voltage and wire feed speed at the feeder,
saving time and increasing weld quality because optimal
weld parameters are easy to set.
