• 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.

Bernard BTB Gun 300 A MIG gun with AccuLock™ S consumable system features a dual-locked, front-loading liner that optimizes wire feedability.

• Install AccuLock contact tips with a single turn.

• AccuLock liner locks at front and back of gun to align with contact tip and power pin for a flawless wire feed path.

• Durable, ergonomic handle improves grip and comfort.

Program mode allows easy save and recall of favorite weld settings.

• Delivers greater productivity by eliminating the need to manually set or change parameters.

• Deliver consistent quality by welders of all skill levels by using prequalified weld settings.

• Minimize supervisor need to intervene.

Easy to Use

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.

Ratings A, B, C, and D are relative values. An “A” rating indicates a best fit between your performance needs and process. A “blank” rating indicates that the process is not recommended for that application.

COLDHOT

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.

Auto-Gun Detect™ automatically adjusts voltage, wire speed and timers for faster switching between MIG, push-pull and spool guns.

GENERATOR

COMPATIBLE

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.

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.
