Extra to the ordinary

KEY BENEFITS

WELD ASSIST

Take the guesswork out of

MMA parameter setting with

Weld Assist, lowering setup

speed by up to 60 % and

ensuring suitable parameter

setup the rst time and every

time.

HIGH QUALITY

MMA WELDING

Perfect welds are characterized

by a smooth, controlled arc

performance. Master 315 has

the dynamic performance to

keep the arc under control,

including cellulosic electrodes.

WIRELESS REMOTE

CONTROL

Extend usability and eliminate

hazards with the HR45

Bluetooth wireless remote

control. Simple and safe power

setting and memory channel

selection up to 100 m from

your workstation.

Master 315 is a stylish and practical MMA welding machine, capable of absorbing the knocks and
impacts of everyday welding life. Lightweight and compact, the Master 315 is constructed from tough
injection molded plastic, featuring impact bridge protection structures, making it your reliable partner
for workshop or site use.

Master 315 guarantees optimal welding performance and fast parameter setting, supported by the
innovative Weld Assist menu selection tool. Weld Assist ensures suitable parameters are set for each
application, regardless of your welding experience. Select the electrode type, electrode size and joint
type, and Weld Assist makes the perfect setting for you.

MMA welding may be a basic welding process, but Master 315 adds the extra to the ordinary in a
perfect blend for professional welding.

Fast and accurate setup,

premium weld quality

PULSED MMA

Superb user experience

FAST AND ACCURATE SETUP WITH WELD ASSIST FUNCTION

Weld Assist sets your target range parameters fast, guiding every welder towards
accurate, productive welding.

5

For selected applications, Pulsed MMA can
lower the overall heat input, improve welding
arc control and increase welding speed.
Additional bene ts of Pulsed MMA include
excellent positional and root pass welding
properties, cleaner welds and reduced heat
deformation.

ARCBREAK TECHNOLOGY

ARCbreak technology provides welding
professionals a variable parameter setting to
easily make and break the welding arc during
MMA welding.

With better control of the weld pool and
heat input, ARCbreak helps you avoid burn
through, improves overall weld quality and
increases tack welding speed. ARCbreak can
be optimized through the Weld Assist menu
for variable electrode types.

Follow the simple on-screen steps, by selecting the electrode type, electrode size
and joint con guration and hit your best parameters with ease. Perfect for pWPS
creation.

CELLULOSIC WELDING
PERFORMANCE

Cellulosic welding electrodes require a large
voltage reserve for reliable welding. Master
315 has a special welding program and
tuned power dynamics, ensuring the unique
arc force properties for excellent cellulosic
welding performance.

MEMORY CHANNELS

Master 315 includes 99 memory channels for
your best parameter settings or WPS values.
Copy or delete and update as needed. It’s fast
and simple.

THE MAGIC OF CORDLESS REMOTE
CONTROL

Select the HR45 Bluetooth remote control and enjoy
wireless power or channel control from a distance of up
to 100 meters.

Eliminate the need for remote cable repairs and improve
worksite safety by using the HR45 Bluetooth wireless
remote.

Make welding life easy.

TECHNICAL DATA

BASIC TIG WELDING FUNCTION AND FLEXLITE TX TORCHES

Connect a Flexlite TX223GVD134 torch and shielding gas, select suitable
welding parameters for the TIG welding task and you’re ready to ignite the
welding arc. With a gentle touch of the tungsten electrode to the workpiece,
Master 315 provides an excellent power source for quality DC TIG welding.

Flexlite TX series are quality TIG torches for professional welding. Model
TX223GVD134 includes a gas valve for adjusting the shielding gas ow, and
high-strength, exible molded silicone handles reduce wrist loading, lowering
welder fatigue and improving comfort.

OPTIMAL WELDING PARAMETERS FOR
EVERY JOB

Equipped as standard with a full-color 7-inch TFT
display, Master 315 denes the best user experience and
accuracy for weld parameter setting and control.

The easy-to-use navigation buttons and the multi­function control knob, makes it is easy to nd the
optimal welding parameters for every job.

Either select your own settings manually or allow
Weld Assist to guide them for you. Welding machine
control and setting does not get any easier.

PERSONALIZE

Upload your company logo, contact details or favorite
image to the Master 315 screen saver. It’s simple and
fast.
