Arc welding machine Dedra DESI211BT — single-phase inverter, portable, 1 pc

Dedra DESI211BT is a portable MMA/arc welding inverter that delivers up to 200 A output for manual metal-arc welding. The compact design and light weight make it suitable for on-site repair, workshop tasks and hobby projects. The unit supports common types of coated electrodes and provides a stable arc with controlled current delivery, while offering simple front-panel controls for setting welding parameters and monitoring basic operational status.

Advantages

The inverter topology ensures efficient power conversion and lower energy consumption compared with traditional transformer welders. Built for portability, the unit includes ergonomic carrying features and a compact footprint to simplify transport and storage. Its stable arc performance reduces spatter and improves bead consistency across a range of electrode diameters. Clear controls and rapid current response help both experienced welders and occasional users obtain reliable welds with minimal setup time.

Suitable for

• Maintenance and repair tasks on metal fixtures and equipment
• Construction site welding for small structural elements
• Workshop fabrications and metalworking projects
• Hobbyist and DIY welding tasks

Key specifications

• Maximum welding current: 200 A
• Welding process: MMA / Manual Metal Arc (stick welding)
• Electrode compatibility: standard coated electrodes for MMA welding
• Portable, compact housing suitable for mobile use
• Front-panel controls for current adjustment and operation
• Designed for stable arc performance and reduced spatter

How to use

Connect the inverter to a suitable mains supply according to the local electrical requirements, attach the earth clamp to a clean metal surface on the workpiece, and secure the electrode holder. Select an electrode type and diameter appropriate for the material and set the current on the front panel to match the electrode recommendation. Strike and maintain the arc while moving steadily along the joint; adjust travel speed and current as needed to obtain the desired bead profile. After welding, allow the workpiece to cool before handling and inspect the weld for continuity and quality.

Usage recommendations

Use appropriate personal protective equipment including welding helmet, gloves and protective clothing. Choose electrode type and current setting based on material thickness and joint design. For best results, prepare surfaces by removing rust, paint and contaminants, and ensure proper grounding and ventilation during operation.
