Description
Miller® Multimatic® 255 Multiprocess Welder 907728
The Miller® Multimatic® 255 multi-process welder is a 350 amp, portable welder that is capable of MIG, Pulsed MIG, Stick, DC TIG and DC Pulsed TIG welding. The Multimatic® 255 comes complete with full color seven inch LCD screen with Auto-Set™ Elite technology. Auto-Set™ Elite sets MIG, Stick and TIG welding parameters automatically, all you need to do is enter metal thickness and welding wire or tungsten electrode diameter. In addition to built-in welding programs, the 255 can also store your custom welding programs. It seamlessly switches between welding with standard MIG gun or optional Spoolmatic™ spool gun. The 255 also features direct plug for XR push-pull gun for professional aluminum wire feed capability. This allows you to use 12 inch spools of aluminum MIG wire instead of the more expensive 1 lb rolls used with the spool gun.
The Multimatic® 255 runs on 208 to 575 volt input power, using Miller's Auto-Line™ technology that automatically detects input voltage. It comes complete with MIG welding gun, shielding gas regulator with hose, stick electrode holder and ground clamp. TIG welding kit is sold separately.
Processes
MIG (GMAW)
Pulsed MIG (GMAW-P
Stick (SMAW)
Flux Cored (FCAW)
DC TIG (DC GTAW)
DC Pulsed TIG (DC GTAW-P)
Features
Multiprocess capabilities include MIG,
flux cored, DC stick (6010) and DC Lift-Arc™
TIG welding. The Multimatic 255 also
has pulsing capability that allows it to do
pulsed MIG and TIG welding.
Intuitive color LCD user interface makes it
quick and easy to adjust parameters.
Auto-Set™ Elite offers
predefined weld settings to
increase ease of use and
ensure that the job is done
right for operators of all
skill levels.
Available for MIG,
pulsed MIG, stick and
DC TIG processes with the ability to fine-tune your settings.
Set weld parameters by selecting:
MIG (shown)—wire and gas type, wire diameter and material thickness
Stick—electrode type, electrode diameter and material thickness
DC Lift-Arc™ TIG—remote on/off, tungsten diameter and material thickness
Program mode allows easy
save and recall of favorite
weld settings.
Save up to four programs
for each process.
Deliver more productivity
by eliminating need to
manually set parameters.
Deliver consistent quality
by welders of all skill levels
with prequalified settings.
Minimize supervisor
intervention.
Compatible with push-pull MIG guns. Increases productivity by
allowing the use of 12-inch wire spools versus a spool gun’s 4-inch
spools. Reduces downtime from changing wire spools.
Auto-Gun Detect™ automatically adjusts voltage, wire speed and timers
for faster switching between MIG, push-pull and spool guns.
Auto-Line™ allows for any single-phase
input voltage hookup (208–575 V) with no manual linking, providing
convenience in any job setting. Ideal solution for dirty or unreliable power.
Pulsed MIG welding delivers higher quality
welds for ALL welders.
Lower heat input for less distortion on
thin materials and better puddle control
on out-of-position welds.
Less spatter minimizes post weld grinding
and rework, allowing more welding time.
Perform welding applications that couldn’t be done in the past.
Ideal for MIG welding aluminum and stainless steel.
