Quick detail
The COROTC MMA-500 is a 20-400A stick welder on AC 380V ±15% 3-phase input with an 11KW rated input. It is specified with a dual-module design, VDR, generator compatibility, 80V no-load voltage, a 60% duty cycle, IP21S protection, 14kg weight and 480 × 260 × 450 mm dimensions.
product description
The MMA-500 is built around a dual-module architecture and an 11KW input on a three-phase supply. A 20-400A range with a 60% duty cycle and 80V no-load voltage defines the output envelope, while VDR and generator compatibility are listed as separate features of the power stage. IP21S protection is the stated enclosure rating.
Dimensions of 480 × 260 × 450 mm and a 14kg weight place it in the transportable industrial class rather than the handheld band. The AC 380V ±15% tolerance is the listed supply range, and generator compatibility is included as a stated configuration option.
Product specification
l Dimensions: 480 × 260 × 450 mm
l Design: dual module
l Features: VDR, generator compatible
l Series: MMA
l Supply: AC 380V ±15% 3-phase
product application
A 20-400A range on three-phase input suits heavy fabrication and plant maintenance where higher output and longer work cycles are required. The listed generator compatibility covers installations supplied from a generator set.
product features
l 20-400A range, 60% duty cycle, 80V no-load voltage
l Dual-module design with VDR
l Generator-compatible power stage
l IP21S enclosure, 14kg, 480 × 260 × 450 mm
product advantage
The dual-module design, VDR and generator compatibility are listed together, so the MMA-500 can be evaluated as a complete industrial power stage rather than by current range alone. Its ±15% input tolerance is stated explicitly for supply planning.
