Features
Easy-to-understand interface
7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time.
Pulsed MIG welding delivers higher quality
Lower heat input for less distortion on thin materials, less spatter minimizes post weld grinding and rework allowing more welding time. Perform welding applications that couldn’t be done in the past.
Program mode allows easy save and recall of favorite weld settings.
Deliver more productivity, consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need to intervene.
Trigger Program Select
Increases productivity by eliminating the need to go back to the machine to change weld settings. Simply tap gun trigger to select the program.
Capabilities include MIG, pulsed MIG and flux-cored welding.
Bernard BTB Gun 300 A MIG gun with AccuLock™ S consumables
AccuLock liner loads from the front and locks at the front and back to insure proper alignment for flawless wire feed path. New rubber overmold and ball -and-socket handle design improves grip and reduces welder fatigue. New Industrial Bernard AccuLock™ S contact tips provide superior Spray and Pulsed MIG arc performance.
Portability - Machine only weighs 63 lb
Weight is reduced to make it easier to take the welder to where the work is, plus the added convenience of one machine versus two or more.
Optional EZ-Latch™ running gear
Operators no longer need to use lift truck to load machine and running gear into the truck. Latches secure machine to running gear. Simply loosen the latch retaining knob and rotate latches to disengage machine from running gear for easy portability.
The Millermatic 355 will be able to operate and provide full output when powered by generators with 19000 Watt (19K) output or higher. Limited output will occur when used with smaller generators.
Provides control of the weld parameter ranges minimizing deviations from the welding procedure specifications (WPS).
Provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
Input Voltage Selection Switch
Provides versatility to utilize any single- or three-phase North American power (208, 240, 460, 575 V). Location in the wire drive compartment provides the ability to manually switch input voltage. An error will display if wrong input selected.
Auto-Set™ Technology
Offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.
