Arc welding machine Dedra DESI151BT 151A 230V

The Dedra DESI151BT 151A 230V arc welding machine is a compact inverter designed for manual metal arc (MMA) welding. With a maximum output current of 151A and single-phase 230V supply, it is intended for general-purpose welding of steel and other common metals. The unit's compact design and relatively light weight allow for straightforward transport and storage, while its control panel provides simple current adjustment for matching electrode type and material thickness.

Advantages

This arc welding machine offers a stable welding arc at currents up to 151A and is compatible with standard MMA electrodes. Its inverter technology delivers efficient power conversion and reduced idle consumption compared with older transformer-based units. The compact housing and carrying handle make it suitable for jobsite use and storage in a workshop. Controls are straightforward, enabling rapid setup and adjustment for different welding tasks.

Suitable for

• General steel fabrication and repair work
• Maintenance and small- to medium-sized construction tasks
• Hobbyist and DIY welding projects
• On-site repairs where portability is required

Key specifications

• Welding method: MMA (manual metal arc) / stick welding
• Maximum welding current: 151 A
• Supply voltage: 230 V single-phase
• Duty cycle: suitable for light to medium duty (refer to manufacturer documentation for exact duty cycle at rated current)
• Electrode compatibility: standard coated welding electrodes for MMA
• Cooling: forced air cooling

How to use

Prior to use, check that the supply voltage is 230 V and that the mains connection and grounding meet local safety regulations. Fit the correct electrode holder and ground clamp, select an electrode appropriate for the material and set the welding current according to electrode diameter and manufacturer recommendations. Strike the arc with suitable technique, maintain correct arc length and travel speed, and observe safe welding practices including use of PPE (welding helmet, gloves, protective clothing). Allow the unit to cool if used continuously for extended periods and follow any thermal cut-out indications.

Usage recommendations

For consistent weld quality, use electrodes in good condition and match current settings to electrode type and thickness. Ensure adequate ventilation in the working area and periodically inspect cables, connections, and cooling vents. Consult the manufacturer's user manual for detailed duty cycle information, maintenance procedures, and safety instructions.
