Millermatic 255 Auto-Line MIG Welder (208-575V) w/EZ-Latch Running Gear 951000271

Miller® Millermatic® 255 Auto-Line™ MIG Welder (208-575V) with EZ-Latch™ Running Gear 951000271

The Miller® Millermatic® 255 Auto-Line™ MIG welder with EZ-Latch™ single cylinder running gear is a complete 250 amp welding package that comes standard with pulsed MIG welding capability and automatic single-phase, 208 to 575 input voltage detection. The inverter design means that the Millermatic 255 is less than half the weight of its popular predecessor, the Millermatic 252. Auto-Line™ allows for operation on any single-phase input voltage between 208 and 575 volts without manual linking. Auto-Set™ Elite technology allows you to use preset welding parameters based on metal thickness, shielding gas and welding wire type to achieve optimum welds. You can also set your voltage and wire feed speed manually, for a custom welding arc.

The Millermatic® 255 Auto-Line comes complete with full color seven inch LCD screen with intuitive design and simple controls. In addition to built-in welding programs, the Miller 255 Auto-Line can also store your custom welding programs. It seamlessly switches between welding with a standard MIG gun or an optional Spoolmatic™ spool gun. The 255 also features a 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.

EZ-Latch™ running gear with single cylinder cylinder rack gives unmatched portability to the Millermatic 255. For moving around the shop, the 255 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.

NOTE: EZ-Latch™ running gear comes in separate box and requires some assembly. Components assemble in three steps and include: cart with front caster wheels, cylinder tray with rear wheels and cylinder post.

Miller 255 Auto-Line MIG Welder Features:

EZ-Latch™ single cylinder running gear
Provides unmatched portability for the Millermatic® 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.

Easy-to-understand interface with 7-inch color LCD display
Ensures proper machine setup and parameter selection, reducing setup time and increasing weld time. Quick-access backlit Auto-Set and Pulse buttons above the LCD display illuminate when active. Soft-key buttons below the display change function depending on which screen is displayed. Makes setup or change quick, easy and intuitive. Large text for easier readability. Intuitive connection setup images. Full troubleshooting descriptions versus help errors and look up codes.

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 and pulsed MIG processes with the ability to fine-tune your settings. Set weld parameters by selecting wire and gas type, wire diameter and material thickness.

Auto-Line™
Provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single-phase power without removing the covers to re-link the power source. Wondering if you have the correct machine for the shop or the job site is no longer a conern. Auto-Line is also an ideal solution for dirty or unreliable power.

Program mode
Allows easy save and recall of favorite weld settings. Deliver more productivity by eliminating the need to manually set the parameters. Deliver consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need to intervene.

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.

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 changing wire spools.
