Portable welding machine (welding) MEAKIDA MIN-300 (300 A)

The MINI-300A is a compact and powerful inverter-type welding machine designed for welding metal structures, pipes, frames, and various metal parts. The device operates on a single-phase 220V network and is distinguished by high amperage, a stable arc, and reliable operation in everyday conditions.

The machine is equipped with a modern electronic control system that ensures easy arc ignition, precise current adjustment, and overheating protection. Its compact size and ease of use allow it to be used both in workshops and on construction and installation jobs.

The model complies with the international standard IEC 60974-1, which means safe and stable operation even under professional conditions.

Explanation:

Standard • IEC 60974-1 — international standard for arc welding machines (safety and operating modes)
Supply voltage: (U1) • 220V
Operation from a single-phase network (household 220V)
Open-circuit voltage: (U0) • 67V
Open-circuit voltage — ensures easy arc ignition and stable start
Output current range • 20A – 300A
Wide range of working current adjustment for materials of different thicknesses
Output voltage: (U2) • 32V (maximum mode)
Standard operating voltage at high current mode
Duty cycle (Duty Cycle — X) =X • 60% — 300A
Means that in a 10-minute cycle:
the machine operates for 6 minutes at full load (300A)
and requires 4 minutes to cool down: X • 100% — 232A
the machine can operate continuously at 232A without overheating
This is a very important parameter in practice.
Input current: Imax • 52A
Maximum consumed current at peak load: Ieff • 40A
Average effective consumption — important for selecting the breaker and cable
Practical recommendation:
Minimum recommended:
Breaker • 40–50A
Cable • 6–10 mm²
Protection and construction data:
IP21S • Protection class means: IP21 - protected against:
solid particles larger than 12 mm
vertical water drops, i.e.: intended for indoor work
Not intended: for outdoor work in the rain without protection
