This guide covers commonly used original OTC contact tips. The K‑series (e.g. K980C23) are typically used for manual welding, while the L‑series (e.g. L7250B01) are designed for robotic applications. However, some K‑series tips like K980C31 are also compatible with robots, offering a cost‑effective alternative. All items listed are genuine OTC Daihen spare parts, with model numbers and specifications for easy identification.

The K‑series tips are generally used for manual welding, while the L‑series are intended for robotic applications. Although robot tips are typically more expensive, the K980C31 (1.0mm 40L) is a popular choice that works well on robots, helping users save costs. Our headquarters runs promotions on OCT contact tips every June and December – ideal for stocking up if you have high volume usage.
