A professional-grade machine combining Synergic MIG, Manual MIG, Flux-Core, Spool Gun Aluminum MIG, HF TIG, Stick, and Plasma Cutting. Designed to handle a wide range of metal fabrication and repair tasks in a single compact unit.
- Synergic MIG Mode: Automatically matches voltage based on selected wire feed speed for simplified setup and consistent weld quality.
- Manual MIG Mode: Enables independent control of voltage and wire speed for fine-tuned performance.
- Spool Gun Ready: One-button activation for aluminum welding with auto-switch to Manual MIG mode.
- Wire Compatibility:Fe/SS: 0.8mm, 0.9mm: Aluminum: 0.9mm, 1.2mm
- Gas Options: Supports FLUX (gasless), Ar 100% (AL), CO₂100% (Fe), and mixed shielding gases.


HF TIG enables non-contact arc initiation, improving weld start quality and minimizing tungsten contamination. Designed for DC TIG applications on stainless steel and carbon steel.
Note: TIG mode does not support foot pedal operation.
Optimized for stable and reliable stick welding performance, this machine includes the following pre-configured, non-adjustable features:
- Hot Start – Improves arc ignition by momentarily increasing current during start-up.
- Arc Force – Enhances arc stability, especially under low-voltage conditions.
- Anti-Stick – Automatically reduces current to prevent electrode sticking.
These features are factory-set and not user-adjustable, ensuring consistent operation without the need for manual tuning.
