جهاز اللحام بالقوس الكهربائي (Helvi) موديل (Progress 35B)

With a 25–200 A operating range, you can weld thin sections with lower current and move up to higher current for thicker metals. Set the current according to electrode size and material thickness to balance penetration and bead quality.

It includes an adjustable current regulator, inductance control, arc-force adjustment, and a mechanical timer. The current regulator sets heat, inductance shapes the arc for stability, arc-force helps maintain arc stability on different materials, and the timer helps manage arc length for consistent results.

The anti-stick heat shield helps prevent the electrode from sticking during welding and allows quick arc restarts, reducing interruptions and improving overall control.

The welder includes a built-in cooling fan to prevent overheating and an LED display for easy monitoring of current and settings during welding.

SMAW with appropriate electrode types is primarily used for ferrous metals such as mild steel and stainless steel. Aluminum and other non-ferrous metals typically require different processes or electrode types.

1) Ensure you have a suitable power source and connect the welder. 2) Install the electrode and set the current for your electrode and material. 3) Adjust inductance and arc-force as needed. 4) Use the mechanical timer if you want a timed arc. 5) Strike an arc, maintain a steady hand and travel speed, then finish by turning off after welding.

Wear appropriate PPE (welding helmet, gloves, jacket, and eye protection), ensure proper ventilation, keep flammables away, ground the workpiece, and inspect cables and connections before each use.

The 50B is a larger model with a higher potential amperage, thicker-material capability, and potentially a more robust duty cycle. The 35B offers portability and a wide 25–200 A range in a lighter frame, making it well-suited for fieldwork and smaller projects.

The 40B sits between the 35B and 50B in capability; it may offer intermediate power and feature differences. The 35B is designed for portability with strong performance across a broad range. For details, visit: https://fepy.com/product/helvi-progress-40b-stick-welder

High-power welders from Fepy tend to offer higher current with different duty-cycle ratings and additional controls. The 35B focuses on portability with robust current control and anti-stick features, making it a versatile choice for a wide range of ferrous welding tasks.

Yes, for many users the 35B delivers a strong balance of power (25–200 A), portability, and advanced controls (inductance, arc-force, timer, anti-stick) in a compact package. Consider your typical projects, required material thickness, need for field portability, and how important precise heat control and arc stability are to your workflow.

It's well-suited for home garages, automotive repairs, general metal fabrication, and maintenance tasks where reliable, adjustable welding is needed in a compact, portable form factor.
