Millermatic 355 w/XR-A Aluma-Pro 25 ft. & EZ-Latch 951927

Millermatic® 355 MIG Welder with XR-A Aluma-Pro™ 25 ft. & EZ-Latch™ Single Cylinder Running Gear 951927

The Millermatic® 355 with XR-A Aluma-Pro™ 25 ft. push-pull gun is designed specifically for production aluminum MIG welding. The XR-A Aluma-Pro™ air-cooled MIG gun is designed to deliver optimum results when feeding aluminum MIG welding wire and other soft alloy wires and has 25 ft. leads. The XR system offers the versatility to handle everything from light-gauge to heavy-plate applications. This complete aluminum package also includes an EZ-Latch™ single cylinder running gear.

NOTE: Additional standard MIG gun IS NOT included in this package.

The Millermatic 355 is a 350 amp portable MIG Welder that operates on single or three-phase input power. It can even be plugged into a portable generator (full output with 19kW generator). The 355 welds material from 22 gauge to 1/2 in thick in a single pass. It comes standard with pulsed-MIG capabilities and a 7-inch color LCD display screen. Its inverter design means that the Millermatic 355 is less than half the weight of its popular predecessor, the Millermatic 350P.

The Millermatic 355 is perfect for fabrication, manufacturing, maintenance and repair. 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 and save your favorite settings for a custom welding experience. Pulsed-MIG welding capability provides even better weld quality and improved productivity on all metals, including thin-gauge aluminum and stainless steel. Auto-Gun Detect™ automatically senses what type of gun is plugged in: MIG gun, spool gun or push-pull gun. This makes for quick, easy changes between welding applications.

EZ-Latch™ running gear with single cylinder cylinder rack gives unmatched portability to the Millermatic 355. For moving around the shop, the 355 attaches to the running gear through a series of four, quick-disconnect latches. For times when your 355 is taken into the field, the machine and running gear can be quickly separated for loading into a vehicle. The 355 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.

Features

Miller® XR-A Aluma Pro™ Push-Pull w/25 ft. leads
300 amps @ 100% duty cycle Is designed to deliver optimum results when feeding aluminum MIG welding wire and other soft alloy wires. XR system offers the versatility to handle everything from light-gauge to heavy-plate applications.

EZ-Latch™ single cylinder running gear
Provides unmatched portability for the Millermatic® 355. 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.

1- or 3-phase input power
Provides versatility to utilize any North American power (208, 230, 460, 575 Volts).

Program mode
Allows easy save and recall of favorite weld settings.
Delivers greater productivity by eliminating the need to manually set or change parameters.
Delivers consistent quality by welders of all skill levels by using prequalified weld settings.
Minimizes supervisor need to intervene.

Trigger program select
Increases productivity by eliminating the need to go back to machine to change weld settings. Simply tap gun trigger to select the program.

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.

Superior aluminum performance.
Direct connection for included XR™ push-pull guns or OPTIONAL Spoolmatic® spool gun.
Auto-Gun Detect™ automatically adjusts voltage, wire speed and timers for faster switching between MIG, push-pull and spool guns.

Industrial, 4-roll wire drive system
Features two easy-to-set, scaled, tension adjustments and quick-change reversible drive rolls for .035 and .047 in (0.9 and 1.2 mm) wire.

Input voltage selection
Switch located in the wire drive compartment provides the ability to manually switch input voltage. An error message will be displayed if the wrong input voltage is utilized.

Generator compatible
The Millermatic 355 will be able to operate and provide full output when powered by generators with 19,000-watt (19 kW) output or higher. Limited output will occur when used with smaller generators
