Detailed Technical Specifications & Compatibility
Choosing the correct back cap ensures optimal torch balance and prevents gas leaks that can lead to weld porosity.
| Specification | Technical Detail |
| Compatible Torch Series | WP-17, WP-18, WP-26 (Standard Industry Series) |
| Material | High-impact industrial phenolic or reinforced polymer |
| Internal Connection | Brass threaded insert for secure mechanical locking |
| Sealing Component | Heat-resistant silicone or nitrile O-ring |
| Electrode Size Range | Accommodates diameters from $0.040″$ to $5/32″$ ($1.0 \text{ mm}$ – $4.0 \text{ mm}$) |
| Length Type | Long / Extended (for standard $175 \text{ mm}$ tungsten) |
Technical Usage Details:
-
Application: Best used in open-access welding areas where torch clearance is not restricted.
-
Sealing Integrity: The integrated O-ring (typically red or black) must be inspected regularly to maintain a 100% argon seal.
-
Thread Pitch: Standard 57Y02 equivalent threading for seamless integration with existing torch heads.
-
Weight Balance: The long profile provides a counter-balance to the torch, often preferred by operators for steadier hand movements during long weld runs.
