OTC Orifice-Baffle
Description
Technical specification
OTC Daihen Ceramic Orifice‑Baffle for MIG Torches
The OTC Orifice‑Baffle (also known as gas diffuser) is a small ceramic component designed for 350 A Panasonic-style and OTC Blue Torch MIG systems, typically part numbers like U4167G02, U4173G02, etc. Installed between the nozzle and contact tip, it guarantees laminar shielding gas flow, essential for stabilizing the arc and reducing spatter.
Key Functions & Benefits
-
- Laminar Gas Flow
Engineered to create a steady, turbulence‑free gas stream around the weld zone, optimizing shielding and increasing weld quality. - Spatter Prevention
The precision-bored orifice discourages welding spatter from contacting the tip and nozzle, reducing downtime and part replacements. - Hard-Wearing Ceramic Construction
Crafted from high-grade ceramic, the diffuser withstands heat and maintains flow stability under demanding industrial welding.
- Laminar Gas Flow
Compatible Part Numbers & Torches
Most freestanding MIG guns and robot torches rely on different diffuser part numbers. Common references include:
-
- U4167G02 – for OTC/Blue Torch II 350 A air‑cooled torches
- U4173G02 – for higher-power 500 A torches
Other variants include U4665C01, U2526D03 (plastic/thermoplastic), and U2774E03 (for other torch families)
Warranty & OEM Availability
These diffusers are genuine OTC/Daihen consumables, often stocked by welding suppliers worldwide. They are sometimes cross-listed with Panasonic consumables due to shared torch interface compatibility
Why Install a New Orifice‑Baffle?
-
- Maintain excellent shielding – Proper gas coverage reduces porosity
- Protect internal torch components – Saves on tip/nozzle replacements
- Ensure stable arc performance – Less spatter = consistent welds
- Reduce maintenance downtime – A small part with major impact
The OTC Orifice‑Baffle is a critical consumable for maintaining weld quality, torch longevity, and operational efficiency in MIG welding shops. Lightweight, ceramic-built, and compatible with Blue Torch II systems, it ensures predictable gas coverage and low spatter through precision engineering.
