Miller XMT 350 CC/CV Multioperator Pack 350A Industrial Multi-Process Welding System

The Miller XMT 350 CC/CV Multioperator Pack is designed for industrial welding operations that need multiple welding stations from a centralized, rack-mounted system. Built around Miller XMT 350 CC/CV inverter power sources, the system is available in 4-pack and 6-pack configurations, providing multiple 350-amp welding power sources in a compact multioperator setup.

The XMT 350 CC/CV is a versatile multi-process welding power source designed for MIG, flux-cored, Stick and DC TIG welding, with additional capability for air carbon arc cutting and gouging when properly configured. Miller’s XMT rack systems allow multiple XMT power sources to be installed together, making them suitable for fabrication facilities, construction operations, shipbuilding, repair facilities, rental fleets and other environments where several welders may need to work simultaneously.

Available 4-Pack and 6-Pack Configurations

Choose the configuration that matches the number of welding stations required for your operation.

4-Pack

The 4-Pack configuration is designed to accommodate four XMT 350 power sources in a multioperator rack system.

This configuration is well suited to operations requiring multiple simultaneous welding stations while maintaining a centralized equipment layout.

6-Pack

The 6-Pack configuration accommodates six XMT 350 power sources, providing additional welding capacity for larger fabrication facilities, construction operations and high-production environments.

Miller documentation identifies XMT rack systems capable of holding up to six XMT 350 models.

Important: Exact rack configuration, power distribution components, connectors, cables, feeders, controls and other accessories vary by package. Review the selected configuration or contact Prime Welding Supply before ordering if you require a specific system configuration.

Miller XMT 350 CC/CV Power Source

At the center of the system is the Miller XMT 350 CC/CV, Stock No. 907161, a 350-amp inverter welding power source designed for demanding multi-process applications.

The XMT 350 uses Miller’s Auto-Line™ technology, allowing the power source to accommodate 208–575V input without manually relinking the machine for different input voltages.

Its CC/CV output makes the machine suitable for a broad range of welding applications, from Stick and TIG work to MIG and flux-cored welding when paired with the appropriate wire feeder or other equipment.

Welding Processes

The XMT 350 CC/CV can be used for:

• MIG / GMAW
• Flux-Cored / FCAW
• Stick / SMAW
• DC TIG / GTAW
• Air Carbon Arc / CAC-A cutting and gouging, when properly configured

The power source can be paired with compatible wire feeders, spool guns, remote controls and other equipment through its available connections.

Pulse Welding

Pulse capability should not be confused with the standard XMT 350 CC/CV configuration. Miller identifies the XMT 350 MPa as the XMT 350 model specifically offering pulsed MIG capability. Optional equipment and controls may also provide additional process functionality depending on the system configuration.

Key Features

Auto-Line™ Input Technology

Auto-Line automatically adapts the XMT 350 to the applicable input voltage range, helping simplify equipment deployment when machines are moved between locations with different available input voltages. Miller lists the XMT 350 CC/CV 907161 for 208–575V input.

CC/CV Welding Output

The XMT 350 provides both constant-current and constant-voltage output characteristics, allowing one power source to support multiple welding processes.

Adaptive Hot Start™

Adaptive Hot Start helps improve Stick electrode starts by providing additional starting output when needed.

Infinite Arc Control

Arc control allows operators to fine-tune welding characteristics for different materials, electrodes and welding positions.

Lift-Arc™ TIG Starting

Lift-Arc provides a controlled DC TIG arc-starting method without requiring high-frequency starting.

Fan-On-Demand™

Fan-On-Demand cooling operates the cooling fan when needed, helping reduce unnecessary airflow through the machine and limiting the amount of dust and debris drawn through the equipment.

Wind Tunnel Technology™

Miller’s internal airflow design helps isolate sensitive electronic components from the direct path of airborne contaminants.

Digital Meters

Large digital displays make it easier for operators to monitor and set welding parameters.

14-Pin Connection

The 14-pin receptacle provides compatibility with appropriate feeders, remote controls and other compatible accessories.

Aluminum Housing

The XMT 350 uses a lightweight aluminum housing designed to provide protection while keeping the individual power source relatively easy to handle.

XMT 350 CC/CV Specifications

Always verify the machine rating label and the configuration being purchased for final installation requirements.

Multioperator Rack System

A major advantage of the XMT platform is the ability to combine multiple power sources into a single rack system.

Miller offers XMT racks designed for multiple XMT power sources, including configurations capable of holding four or six XMT 350 units. Rack systems are designed to centralize the equipment and simplify connection to the facility’s primary power supply.

This makes a multioperator configuration particularly useful when several welders need access to individual welding power sources without maintaining a separate standalone machine for every work area.

Typical Applications

The Miller XMT 350 CC/CV Multioperator Pack is suited to demanding environments such as:

• Heavy industrial welding
• Structural fabrication
• General metal fabrication
• Construction
• Shipbuilding
• Railroad fabrication and repair
• Truck and trailer manufacturing
• Equipment repair
• Maintenance operations
• Rental fleets
• High-volume welding facilities

Why Choose a Multioperator System?

A multioperator rack can simplify the way a facility deploys several welding power sources.

Instead of positioning multiple standalone machines throughout a work area, the XMT rack approach allows several XMT power sources to be organized together in a centralized system.

Depending on the configuration, this can help:

• Provide multiple welding stations
• Consolidate equipment in one rack
• Simplify primary power distribution
• Reduce equipment footprint
• Make better use of available welding power sources
• Support different welding processes from individual XMT machines

Miller describes its multioperator rack systems as a way to combine multiple welding power sources into a transportable package for multiple arcs and to improve equipment utilization.

For a complete package quotation or a configuration with specific feeders and welding accessories, contact Prime Welding Supply before placing your order.

Built for Multi-Station Welding

The XMT 350 CC/CV platform is particularly useful when different operators need different welding processes at the same time.

One operator can use an XMT for Stick welding while another machine is configured for MIG or flux-cored welding, while another can be used for DC TIG applications.

This flexibility makes the XMT platform practical for fabrication shops, construction crews and industrial facilities where welding requirements can change throughout the workday.
