Miller Multimatic® 255 Multiprocess Welder w/EZ-Latch™ Dual Cylinder Running Gear & TIG Kit Package 951768
The Miller Multimatic® 255 multi-process welder with EZ-Latch™ dual cylinder running gear and TIG kit is a complete 350 amp, portable welding package 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.
This is a DC only machine. It cannot TIG weld AluminumEZ-Latch™ running gear with dual cylinder and elevated gun & cable rack gives unmatched portability to the Multimatic 255. For moving around the shop, your 255 welder attaches to the running gear through a series of four, quick-disconnect latches. For times when your 255 is taken into the field, the machine and running gear can be quickly separated for loading into a vehicle. The 255 can also be separated from the EZ-Latch running gear to access difficult-to-reach areas around the shop where a welder with full running gear/cylinder rack might not otherwise fit. The elevated gun and cable rack helps keep MIG guns, Spool Guns, TIG torches and cables out of the way for easier movement within the workspace.
NOTE: EZ-Latch™ running gear comes in separate box and requires some assembly. Components assemble in four steps and include: cart with front caster wheels, dual cylinder tray with rear wheels, dual cylinder post and gun & cable rack.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 TIG kit with 150 amp air-cooled TIG torch, MIG welding gun, shielding gas regulator with hose, stick electrode holder and ground clamp.

Features
EZ-Latch™ single cylinder running gear provides unmatched portability for the Multimatic 255. Operators no longer need to lift machine AND running gear when loading or moving. Latches secure machine to running gear. Simply loosen the latch retaining knob and rotate latches to disengage machine from running gear for easy portability. Cylinder rack features bottle forward technology for increased stability when moving along an incline and running gear has built-in storage for accessories.
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.
