WP‑18 Auto‑Pencil Head TIG Torches – 4M & 8M | Water‑Cooled LH Bullnose
The WP‑18 Auto‑Pencil Head TIG Torches are high‑performance, water‑cooled, left‑hand (“LH”) bullnose style torches featuring a “pencil‑head” or auto‑pencil design for fast change‑over of consumables and enhanced precision. Available in 4‑metre and 8‑metre cable/hose lengths to accommodate both bench, field, and automated setups. Ideal for welders or automation rigs that need reliable, high‑amp performance with quick consumable swaps.
Key Features
-
Auto‑Pencil Head
Designed for quick change of cups / nozzles; slim profile bullnose tip allows easier access to tight joints or weld seams. Good for robotic or automated arms or setups where space is limited. -
Water‑Cooled Construction
Helps manage heat buildup, enabling higher continuous current without overheating. Essential for prolonged welds or heavy materials. Provides better durability over air‑cooled in demanding or continuous use. -
LH Bullnose Connector
Left‑hand threaded bullnose fittings for nozzle or hose connections. Secure fit, resistant to loosening under hydraulics/vibration. Ensure compatible bullnose threads for any hose or consumable you use. -
Two Length Options
-
4M version: lighter, more manageable for bench, manual TIG welding, small workstations.
-
8M version: extended reach ideal for large assemblies, robotic cells, or larger machines where extra hose/cable length is needed without moving the power source.

High Current Capacity
Rated for high amperage (typical WP‑18 specs are in the ~350 A DC, 250 A AC region, depending on cooling and nozzle sizes) with capacity to accept tungsten sizes from about 0.5 mm to 4.0 mm, enabling flexibility for light to heavy TIG work. -
Consumables & Compatibility
Comes with standard WP‑18 style consumables: collets, collet bodies, back caps, ceramic cups, etc. Multiple nozzle bore sizes (6 mm, 8 mm, 10 mm, etc.) which are available for matching the weld bead size and gas flow. Rear connector options include LH threaded or DIN style fittings in some variants.
