Product catalog summary

Overview

This document provides technical specifications and features of DC welding rectifiers and related equipment, including current regulation methods and electrical parameters.

Main Sections

1. Equipment Types and Current Regulation

DC Current Rectifiers: Devices converting AC to DC for welding applications.
Current Regulation Methods:
- SHUNT regulation for models SC-355 and SC-405.
- Electronic thyristor regulation for model SC-500.

2. Technical Specifications

Key electrical and physical parameters for various models are summarized below:

Model	Voltage (V)	Phase	Fuse (A)	Peak Current (A)	Welding Current Range (A)	Power (kVA)	Weight (kg)	Dimensions (mm)
SC-355	230	1ph	16	170	40-150	2-4.3	16	385x245x255
SC-405	230	1ph	16	180	40-160	2-5	16	385x245x255
SC-500E	230/400	1ph	30	200	35-180	2-6.2	20	425x255x245
SB-160	230/400	1ph	32	270	35-250	3-12.3	41	300x300x575

Additional three-phase models (SB-1000 TURBO, SB-2000 B TURBO, START-250 B TURBO) feature higher currents and power ratings with detailed duty cycles and protection ratings (IP23).

3. Standards and Operating Conditions

Compliance with EN60974-1 standard at 40ºC ambient temperature.
Operating frequency: 50/60 Hz.
Fuse ratings and peak current values specified per model.

4. Accessories and Equipment Completeness

Some equipment comes complete with accessories such as clamps, brushes, chipping hammers, and hand masks.
Other models are supplied without accessories.

5. Summary of Key Features

DC welding rectifiers with two main current regulation technologies: SHUNT and electronic thyristor control.
Wide range of welding currents suitable for various applications.
Compact dimensions and manageable weights for portability.
Models designed for single-phase and three-phase power supplies.

Critical Information

Ensure correct fuse rating and power supply compatibility before installation.
Observe duty cycle percentages to avoid overheating and equipment damage.
Choose current regulation type based on welding precision and control requirements.
