Models That Deliver Consistency and High-Performance Welding

OTC Robot
Compact Power with Precision

FD-VC4

The FD-VC4 model is optimized for precision welding in small to mid-sized applications. With repeatability of ±0.02 mm, it ensures stable arc performance in CO₂/MAG, TIG, and low-spatter welding processes. This makes it perfect for both spot welding and complex seam tracking, delivering consistent quality every time.<br><br>Additionally, the intuitive user interface allows easy programming—even for first-time robot operators.<br><br>Each OTC COBOT delivers high repeatability (±0.02 mm) and stable arc control, supporting various welding processes such as CO₂/MAG, TIG, and low-spatter techniques. Whether it’s spot welding or complex seam tracking, OTC COBOTS perform with speed, accuracy, and consistency to meet the quality demands of modern manufacturing.

Extended Reach and Maximum Flexibility

FD-VC4L

When you need a longer arm to handle larger components, the FD-VC4L is the solution. This model offers all the benefits of the FD-VC4, plus:

  • Extended reach up to 1,317 mm for bigger workpieces
  • Compact, space-saving frame – easy to install in limited workspaces
  • Certified to international safety standards for peace of mind
  • ±0.02 mm repeatability – ideal for critical weld precision
  • Multiple teaching modes, including hand guidance and tablet control
  • P65-rated durability – withstands dust, sparks, and welding fumes
