The Miller Syncrowave 300 AC/DC is a robust, industrial-class TIG/Stick power source built for demanding fabrication, maintenance, and precision welding tasks. With full AC/DC capability, smart arc control, and built-in cooling, it’s designed to handle a wide range of materials — including aluminium, steel, stainless, and exotic metals — with efficiency and consistency.
?? Key Features & BenefitsAC / DC Capability — Weld aluminium using AC mode and switch to DC for steel, stainless, or pulsed TIG applications.
Auto-Link / Multi-Voltage Input — Automatically adapts to input voltages (208 / 240 / 480 V, single- or three-phase), simplifying installation and reducing setup errors.
Pro-Set™ One-Touch Parameter Presets — Allows users to return all settings to factory presets with a single button, helping limit configuration mistakes and speeding job setup.
Blue Lightning™ / HF & Lift-Arc Start Options — Provides high-frequency arc starts or non-contact Lift-Arc initiation, giving flexibility in sensitive or noisy environments.
AC Waveform & Balance Control — Adjustable balance and AC wave settings let users control oxide cleaning on aluminium and shape the arc to the job.
Pulse DC for Precision & Heat Control — Pulsed DC mode offers enhanced puddle control, higher travel speeds, and lower heat input on thin or sensitive materials.
Stick Welding Support — DIG control for electrode behavior, Hot Start adaptive control, and protection for stick arcs are included.
Fan-On-Demand™ & Cooling Integration — The internal cooler power supply supports the Coolmate 3S system and fan runs only when necessary, reducing noise, power usage, and contamination.
Compact, Durable Design — Built for industrial workloads, with robust construction and user-friendly access to controls and coolant systems.
Duty Cycle / Output — Delivers up to 300 A in DC/AC modes (e.g. 300 A @ 22 V at 30% duty) with strong ratings for heavy use.
