Why Inverter Technology used in Welding Equipment?

The inverter welding machines are much smaller and lighter, more efficient and energy saving compared to conventional welding machines. In addition, they offer better control of welding characteristics such as smooth and stable arc. Hence, inverter technology is well and truly an efficient choice for welding power sources.
 

Why Choose Weldman Welding Equipment?

The WELDMAN brand welding power sources are of heavy-duty type, designed with IGBT based inverter technology for excellent electrical and welding performances. High quality and proven semiconductor components are used for superior reliability and performance.

The WELDMAN power source are designed to work under the harshest environments and to meet the stringent requirements where quality is of paramount importance.

All WELDMAN products undergo stringent Quality Control tests so as to achieve high reliability, endurance and performances. They are suitable for shipyards, pipelines, construction works, petrochemical plants, oil refineries, offshore works and engineering workshop.

Salient Features of Weldman Welding Equipment

Compact and Yet Rugged, Environment Friendly and Reliable
The power magnetic components like main transformer and main choke are extremely small and lightweight despite their high power capacity. The heavy gauge base plate protects the internal components from impacts and knocks encountered during shifting of machine on site, shop floor, on board vessel etc. The magnetic components, live terminals, bus bars and PCBs are protected against fungus, moisture, dust and corrosion by conformal coating. The protection category for remote connectors when connected is IP67.

WELDMAN - Main Transformer

Heavy Duty Welding
The power components are efficiently cooled so as to deliver high welding currents for long hours at high rated duty cycle (70%).

Longer Life Span
The power semiconductor component's lifespan is enhanced by thoughtful and strategic design of forced air-cooling system. The inlet air cools the heat sink fins and power magnetic components. The power semiconductor components and their live terminals are not in the airflow path and are thus protected from dust and moisture. The maximum temperature of the heat sink is 70 °C.

WELDMAN - Heat Sink

Energy Saving and Generator Friendly
Substantial cost savings (20 ~ 30%) can be achieved compared to conventional machines due to higher efficiency, lower input KVA demand and lower no load / load electrical consumption. Cost savings can be up to 90% for no load power consumption alone. The generators are not affected by starting surge current due to fast acting control circuit of WELDMAN.

Supply Voltage Guard
The incorporated input sensing circuit warns and protects the machines against input abnormalities like sustained under / over voltage and single phasing.

Welder's Favourite
WELDMAN has simple panel controls. It is easy to connect and set up. It is also optimized for excellent CC / CV characteristics to suit various welding applications. Digital display on the front panel is a standard feature for easy setting and monitoring of welding current and voltage.
