Designed for professionals who demand maximum performance, this 500A, 415V multi-process welder delivers outstanding output, reliability, and control across the most demanding environments — from structural fabrication to heavy industrial maintenance.
Unmatched Welding Power
With a massive 500A output and 60% duty cycle, the Freedom 540A is built to handle continuous, high-intensity workloads with ease. It’s ideal for fabrication shops, production lines, and on-site applications that require consistent, high-quality welds without downtime.
Smart 5” LCD Control Interface
The sharp, full-colour 5” LCD display offers crystal-clear visibility of all welding parameters, allowing easy adjustments in real time. Operators can fine-tune voltage, amperage, and modes with precision and speed.
Advanced Trigger Modes – 2T / 4T / Spot Weld
Enjoy complete flexibility with multiple trigger options. Whether you’re performing long weld runs or quick spot welding, this machine adapts to your workflow effortlessly.
Remote-Ready with Separate Wire Feeder
The external wire feeder provides extended reach and reduces cable tension, making it ideal for large-scale projects and hard-to-access weld zones.
All-in-One Multi-Process Capability
Harness the flexibility of four core welding processes:
-
MIG (Manual & Synergic)
-
Gas / Gasless MIG
-
DC TIG (Lift Arc)
-
Stick / MMA
Backed by advanced PWM IGBT inverter technology, it delivers smooth arcs, reduced spatter, and consistent penetration for professional results every time.
Built for Real Work Environments
-
Compatible with D200 & D300 wire spools
-
Integrated tool storage compartment
-
Air-cooled and thermally protected for reliability
-
Durable steel frame and trolley design for workshop or field use
Material Versatility
The Freedom 540A handles a wide range of metals — mild steel, stainless steel, copper, brass, and aluminium (MIG) — with accuracy and strength. It’s engineered to deliver clean welds even on thick gauge materials.
