Welding generators industrial and commercial uses in India for more than two decades by Cruxweld all over the country with the best quality products. We produce super silent diesel welding generators in India as a pioneer. The technology gave birth to an advanced product where the dual function of welding and generating is combined to make it more economical for the consumer.

The welding and generating at the same time can be initiated. The welding arc here is super smooth thus making welding in all applications smooth, stable, and strong welding. This is a high-performer brushless welder cum generator with the capacity to produce 400amp DC welding current. It has a big range of utility from heavy fabrications, site constructions, cross country and in-house, and pipe and tube welding in industries. This machine is highly reliable in most hostile environments and situations. This is very fuel efficient and saves money.

The welding current range is 50-400 and the suitable electrode diameter is 2.5 to 6.3. The insulation is H class and has 2 cylinders. The generators have a fuel tank capacity of 40 liters and fuel consumption is 2.6 liters per hour. It can run for 12 hours without any break. and have an auto-shut facility in case of any untoward situation.

Our welding generators are specially developed to meet the requirement of quality welding in assembly work, pipe welding, repair, maintenance, and other welding applications. These are very useful in remote areas where they can be used as standby welding sets in a fabrication establishment. These welding generators are useful for welding mild steel, stainless steel, cast iron, and weldable non-ferrous materials.

We can supply this machine with 100 meters of cable without any current drop. Our products are known for their quality, reliability, and completeness. We supply all over India and export to different countries.
