ACCESSORIES

☑ 3M 200A Electrode Holder Cable x1

☑ 2M Ground Clamp Cable x1

◉ 30–160 A at 220 V and 30–180 A at 380 V

Adjust the current to suit the electrode size and welding job.

◉ Hot start, arc force and anti-stick

Makes arc starting easier, helps maintain the arc and reduces sticking interruptions.

◉ J422, E6011 and E7018 electrode compatibility

Supports common electrode types, including acid-coated and basic-coated options.

◉ Large LED display

Makes settings easy to read and check before welding.

◉ Synergic adjustment

Simplifies setup for users with less welding experience.

◉ Reinforced carry handle

Provides a comfortable, sturdy grip for carrying the machine.

◉ Overheat, overcurrent and voltage protection

Helps protect the machine from excessive heat, current and unsuitable supply voltage.

◉ VRD and soft start

Reduces open-circuit voltage when VRD is active and limits the startup current surge.

◉ Digital control

Welding parameters can be configured at the factory to suit your requirements.

Q1. What welding process does the H-320K support?

A1. The H-320K is a digital DC MMA stick welder designed for manual metal arc welding with coated electrodes. Its inverter-based design provides stable arc performance for steel fabrication, repair, and maintenance work.

Q2. Does the H-320K support both 220V and 380V input power?

A2. Yes. The machine operates on both 220V and 380V power supplies at 50/60Hz. It automatically adapts to the available input voltage, making it suitable for different workshop and jobsite environments.

Q3. What is the output current range?

A3. The output range is 30–160A when connected to 220V power and 30–180A when connected to 380V power. This allows users to adjust the welding current for different electrode sizes and material thicknesses.

Q4. What material thickness can the H-320K weld?

A4. The H-320K is designed for welding steel sections from 1–16mm. Actual welding capacity depends on electrode size, joint preparation, welding position, and operator technique.

Q5. What electrode sizes can be used?

A5. Under 220V input, the machine supports 2.5mm to 4.0mm electrodes. Under 380V input, it can run 2.5mm, 3.2mm, and 5.0mm electrodes, providing flexibility for a wide range of welding tasks.

Q6. Does the H-320K require shielding gas?

A6. No. MMA stick welding uses flux-coated electrodes that create their own shielding protection during welding. No external shielding gas or gas cylinder is required.

Q7. Is the H-320K suitable for portable and on-site work?

A7. Yes. With a machine weight of only 4.2kg and a compact 300 × 140 × 230mm body, the H-320K is easy to transport between workshops, maintenance locations, and field repair sites.

Q8. What technology does the H-320K use?

A8. The machine uses IGBT inverter technology, which helps provide stable welding performance, efficient power conversion, and a compact machine design compared with traditional transformer welders.

Q9. What accessories are included?

A9. The standard package includes a 3m electrode holder cable and a 2m ground cable. Users only need to prepare suitable electrodes and personal protective equipment before welding.

Q10. What applications is the H-320K best suited for?

A10. The H-320K is suitable for fabrication workshops, equipment maintenance, farm repairs, construction projects, metal installation work, and general steel repair applications requiring a compact and reliable MMA welder.
