Welding inverter Heidmann 330 IGBT NEW — Heidmann model H00702

Heidmann 330 IGBT NEW — Heidmann model H00702 is an inverter welding machine engineered for arc welding tasks with coated electrodes. As an IGBT-based inverter unit, it provides a stable welding current and efficient power conversion to ensure consistent performance for metal joining and repair applications. The unit is designed for workshop and professional environments and supports portable use where mains power and standard electrode types are available.

Advantages

The inverter topology delivers improved energy efficiency and reduced weight compared with conventional transformer welders, while IGBT components help maintain a steady arc and reduce spatter. Compact construction and a simple control interface make setup and adjustment straightforward. The device offers reliable thermal protection and efficient cooling to sustain longer operating periods under typical workshop loads.

Suitable for

• Maintenance and repair of steel structures and metal parts
• Workshop fabrication and small-scale production
• Automotive bodywork repair and restoration tasks
• Portable on-site welding where mains power is accessible

Key specifications

• Inverter technology with IGBT switching for stable arc control
• Designed for MMA (coated electrode) arc welding
• Compact and portable form factor suitable for workshop use
• Thermal protection and active cooling to manage duty cycles
• User-adjustable welding current and simple front-panel controls

How to use

Install the welding inverter on a stable, level surface in a well-ventilated area and connect to an appropriate mains supply following local electrical regulations. Fit a suitable earth clamp to the workpiece and select the correct electrode type and diameter for the material being welded. Set the welding current according to the electrode specification and material thickness, strike the arc and maintain a consistent travel speed and electrode angle to achieve uniform weld beads. Allow the unit to cool if thermal protection activates before continuing prolonged welding sessions.

Usage recommendations

Use electrodes and filler materials appropriate for the base metal and joint design. Regularly inspect cables, clamps, and insulation for wear or damage. Operate the inverter in environments free from excessive dust, moisture, or flammable vapors and follow personal protective equipment standards, including appropriate welding helmet, gloves, and clothing.
