The KR QUANTEC prime is geared towards providing the perfect balance between payload and reach. When it comes to spot welding, it is the market leader. The prime achieves outstanding cycle times due to its robustness and high acceleration rates.

The KR QUANTEC prime is virtually unbeatable when it comes to robustness. It has a maximum reach of 2,500 millimeters with a payload of 240 kilograms. Yet it is as streamlined and light as its other family members. As a result, the prime robots are the new performance benchmark in spot welding. As shelf-mounted robots, they are optimized to minimize space requirements and that extends the economical reach range. The foundry variants offer a solution for applications involving dusty, wet and hot environments.

Wide spectrum

The KR QUANTEC prime achieves the perfect balance between payload and reach and opens up a wide range of potential applications. Yet spot welding is the prime’s specialty.

Fast cycle times

The KR QUANTEC prime stands out due to its robust design, yet it is extremely lightweight. It is optimized to achieve fast cycle times by way of high rates of acceleration. This is how it delivers outstanding process results.

Low maintenance requirements

The KR QUANTEC prime fits into every concept. It only requires a small amount of floor space. Even the maintenance outlay has been reduced to a minimum.

Energy-efficient and robust

The KR QUANTEC prime has a very small ecological footprint. Its compact base frame provides a firm footing and a hole pattern that is consistent with the rest of the KR QUANTEC series.
