Projects in this market vary considerably, which results in the critical need for versatility in welding equipment. Superior strength-to-weight ratios, corrosion resistance, sturdy wall joints and aesthetic welds are essential in these applications. Miller aluminum systems offer the flexibility and mobility you need for everything from subassembly to the final weld.

Product Overview

Millermatic® 350P Aluminum MIG System

  • Millermatic 350P Aluminum power source
  • OR XR-Aluma-Pro Lite gun
  • XR-Aluma-Pro™ gun

System features and benefits:
  • Compatible with most Miller Push-Pull guns for consistent wire feeding; expands work envelope up to 35 feet without moving the power source.
  • True torque feed motor push-pull design provides continuous push force to the wire while the gun motor controls the speed at the gun. The motors work together to provide accurate and positive wire feed speed without wire shaving or deformation.
  • Pulsed MIG reduces heat input, resulting in less warping, distortion and spatter — increasing productivity and reducing rework. Ideal for thin gauge materials.
  • Synergic MIG provides communication between power source, feeder and gun. As wire speed increases/decreases, the arc voltage also increases/decreases to maintain a constant welding arc.
  • Easy to use: One-knob synergic welding control sets the correct Pulse parameters based on the wire feed speed set by the operator; allows the operator to adjust to varying joint profiles or material thicknesses.
  • Produces high deposition rates and fast weld speeds for long joints and production welding.
  • Compact, all-in-one welding system with running gear makes it easy to move around the weld cell.

Dynasty® 350 TIG System

  • Dynasty 350 TIG Runner

System features and benefits:

  • TIG inverter benefits include increased productivity, improved quality, energy efficiency and portability
  • Capable of welding a wide range of material, including thin gauge to 5/8" thick aluminum.
  • Precise arc and directional control for accurate weld sizing and placement.
  • Reduced distortion and burn-through on thin and delicate parts.
  • Produces aesthetically pleasing welds with no sparks, spatter or slag, reducing cleanup and finishing time.
  • Advanced AC TIG controls allow for welding anodized aluminum in a single pass - a major increase in productivity.
  • Remote amperage control lets you compensate for changing geometries, varying joint fit-ups, and inconsistencies — without sacrificing weld integrity.

Next Generation Welding Helmets Offer Benefits for Operator Comfort and Productivity

Advanced welding helmet technologies not only ensure operator safety and help meet compliance requirements, but they also offer greater comfort. Having the best possible helmet for the job — and the most comfortable — can add up to greater productivity by reducing workplace injuries and discomfort, and allowing an operator to weld for longer.

An Introduction to Pulsed GMAW

Pulsed gas metal arc welding (GMAW) can offer companies quality and productivity advantages, including for welding operators of varying skill levels. In some cases, companies may be hesitant to adopt the process, but it can offer distinct advantages.
