جهاز اللحام (Helvi) موديل (Mega 350) بالتيار المتردد و المستمر

The Helvi Mega 350 AC/DC Welder is a 350 amp inverter MMA welder that operates on AC or DC. It's designed for everyday use and can weld with electrodes from 0.6 to 1.2 mm, making it suitable for a wide range of metal fabrication and maintenance tasks, including general steel work and light aluminum work when using AC mode.

Key features include a digital display for current and voltage, Hot Start for easy arc initiation, Arc Force control, Anti-Stick to prevent sticking, infinitely variable inductance for fine-tuning, 230V input, portability with a carrying handle, and compatibility with electrodes up to 6 mm.

It delivers up to 350A in AC/DC mode with a 230V input. The welder supports electrodes ranging from 0.6 to 1.2 mm and includes thermal protection to help prevent overload during extended use.

Yes, aluminum welding is possible in AC mode. Switch to AC, adjust the inductance for stableArc, and use appropriate aluminum-compatible electrodes. Keep in mind aluminum welding often benefits from slower travel speeds and a clean, oxide-free surface.

It is designed for a broad range of metals, including steel and stainless steel, with electrodes up to 6 mm. It’s well-suited for general fabrication, maintenance, and light aluminum work on thinner sections.

The Mega 350 is described as portable and lightweight with a carrying handle, making it convenient to move between job sites or around the workshop.

Steps: 1) Place the welder on a stable surface and connect to a suitable 230V outlet. 2) Attach the grounding clamp securely. 3) Use the digital display to set the target current (and voltage if supported). 4) Adjust the inductance for stable arc behavior. 5) Select the appropriate electrode and start welding. 6) If needed, engage Hot Start and Arc Force for better arc initiation and control.

Always wear appropriate PPE (welding helmet with the correct shade, gloves, and protective clothing). Ensure good ventilation or fume extraction, confirm proper electrical grounding, inspect cables and connections for wear, keep flammables away, and allow the machine to cool after heavy use.

Both models share core features like AC/DC capability, digital controls, and electrode versatility. The Mega 350 offers higher maximum output (up to 350A) compared with the Mega 320, which means it can handle thicker welds or faster deposition in some scenarios.

The Mega 500 is a higher-output model designed for tougher or more frequent welding tasks, offering more amperage and potential capability than the Mega 350. For a direct comparison, see: https://fepy.com/product/helvi-mega-500-ac-dc-welder

Ideal for workshop fabrication, maintenance and repair tasks, on-site welding at construction or industrial sites, and projects requiring reliable MMA welding with both AC and DC capabilities, including light aluminum work.

Regularly inspect and clean the ventilation openings, check and clean all cables and clamps, keep connections tight, store the unit in a dry place, avoid continuous overheating by allowing cooling periods, and perform periodic visual inspections for any signs of wear or damage.
