Trigger receptacle oriented in a downward position to reduce
potential damage.
Trigger hold reduces operator fatigue by allowing the operator to
make long welds without having to energize the trigger continuously.
Dual-wire feeders allow two different wire types to be available on
one feeder, avoiding downtime from changing spools and drive rolls.
For MPa Plus Feeders Only! XR-AlumaPro™ Plus and XR™-Pistol
Plus push-pull guns for aluminum. Comes in 15-, 25- and 35-foot
lengths for extended reach with trouble-free, reliable feeding. Gun is
available in either air- or water-cooled versions.

D models add the following features
D-74D
dual feeder
Digital meters for easy viewing of the wire feed speed and voltage.
Remote voltage control allows operator to set voltage at the wire feeder without having to go
back to the power source.
Tachometer feedback to help keep wire feed speed accurate.
DX models add the following features
Four weld programs allow the operators to store four independent welding parameters
reducing welding setup time. (Four programs available per side on dual feeder.)
Adjustable run-in control for improved arc starts.
Adjustable weld sequence control gives operator complete control of the welding
parameters: preflow, run-in, weld time, crater, burnback and postflow.
Welding process range control locks parameters at a set percentage of welding parameters
to ensure welding procedures and quality standards are maintained on the shop floor.
Dual schedule, trigger dual schedule and trigger program select allows operator to switch
welding parameters without readjusting machine, eliminating downtime and enhancing quality.

74 MPa Plus Wire Feeder Features
MPa Plus models have the features of the S/D/DX models and add the following
Alumination™ technology gives you the ability to use the extended reach of a push-pull
system for consistent, versatile and dependable aluminum wire feeding. Alumination gives
you the versatility to handle whatever aluminum welding job you want to tackle.
Synergic Pulsed MIG operation when optimized with the Invision MPa power supplies.
Provides communication between the power source, feeder and gun. As wire speed
increases/decreases, the pulse parameters also increase/decrease to match the right amount
of power needed.
Trigger schedule select allows the operator to select the alternative schedule by quickly
tapping the gun trigger when not welding. When optimized with MPa power sources the
operator can also switch from MIG to Pulsed MIG.
Profile Pulse™ provides
TIG appearance with MIG
simplicity and productivity.
Achieve “stacked dime” weld
bead appearance without
back-stepping. Profile Pulse
frequency can be changed to increase or decrease the spacing between the ripple pattern to
achieve the desired weld appearance.
Accu-Mate™ properly seats the power pin for best feeding performance and prevents
Accu-Mate grooved MIG guns from sliding in the casting.
