Frequently Asked Questions

Can ROBOT torches support continuous welding in automated production lines?

Yes, ROBOT torches like the ROBOT 350S and 501W are specifically designed for continuous operation. With duty cycles of up to 100% at high currents (e.g., 350A or 500A), they are ideal for 24/7 automated production environments such as automotive assembly or shipbuilding. The gas-cooled design combined with optimized neck angles ensures long-term stability and access in confined spaces.

What is the difference between ROBOT 350S and ROBOT 350D?

While both torches handle similar current levels, the key difference lies in their duty cycles and neck design. The 350S offers a 100% duty cycle, making it suitable for continuous welding, while the 350D has a 60% duty cycle, making it better suited for intermittent or repair-based welding tasks. Additionally, the 350S has a 35° gun neck for better reach in complex geometries, whereas the 350D features a 31° neck for balanced performance and accessibility.

Can ROBOT torches handle high-current welding on thick or high-strength steels?

Absolutely. The ROBOT 501W is designed for heavy-duty applications with a 100% duty cycle at 500A (CO₂). It is capable of handling thick materials such as high-strength structural steel (up to 50mm) used in industries like shipbuilding, wind tower fabrication, and mining equipment repair. It also supports hardfacing operations and deep-penetration welding with high reliability.
