Technical Specifications (Typical / Example)

Specification 4M Version 8M Version
Cooling Type Water‑cooled Water‑cooled
Switch / Trigger Handle‑mounted Handle‑mounted
Rating (DC) Up to ~350 A (DC) Up to ~350 A (DC)
Rating (AC) Up to ~250 A (AC) Up to ~250 A (AC)
Tungsten Electrode Range ~0.5 mm to ~4.0 mm ~0.5 mm to ~4.0 mm
Duty Cycle High (often around 100% for rated duty depending on water cooling system) – confirm per model.
Water Flow Rate & Pressure Typical water flow required (depends on cooling unit), pressure and hose sizing should conform to torch spec. Many models specify 1‑2 L/min or certain inlet pressure.
Electrode Sizes / Nozzle Options Multiple collet sizes and nozzle bore diameters available.

Applications & Use Cases

  • Heavy fabrication, shipbuilding, structural steel, and thick plate welding.

  • AC/DC TIG work (e.g. aluminum and steel) with water‑cooled torches to handle the increased heat during AC use.

  • Situations where long continuous welds are common (welding seams, joints) where air‑cooled torches would overheat.

  • Field installations or on-site welders needing more control over arc start (switch) and good cooling.

What’s Included / Optional Add‑Ons

  • WP‑18 torch head with switch/trigger

  • Power + water hoses/cables for 4 m or 8 m lengths

  • Standard consumables (collets, collet bodies, back caps, nozzles) — check if included; some suppliers supply torch only.

  • LH threaded water hose fittings (bullnose style) and matching water connections

  • Protective sheath or cable guard may be optional depending on model

  • If using water cooling, required accessories such as coolant supply, water cooler unit, fittings, return hoses etc.

Installation & Maintenance Notes

  • Ensure your water cooler or coolant supply matches the torch’s cooling requirements (flow rate, temperature, pressure) to avoid overheating.

  • Use compatible tungsten electrode size for expected current; undersized tungsten will fail or degrade weld quality.

  • Regularly check thread fittings (LH bullnose), junctions, hose integrity, switch condition, water leak potential.

  • Purge water from torch after use to avoid corrosion or damage if torch sits idle.

  • Keep ceramic nozzles / gas cups clean for good gas flow and shield quality.

Description

WP‑18 TIG Torches with Switch – 4M & 8M | Water‑Cooled (LH Bullnose)

Heavy-duty water-cooled TIG torches designed for high-current welding applications. These torches include a handle‑mounted switch for arc control and come in two lengths—4 meters and 8 meters—to suit both tight workspaces and large fabrication areas. The ‘LH Bullnose’ LH (Left-Hand thread) style connector at the nozzle or hose fittings ensures secure installation and compatibility with water hoses having matching threads.

Key Features & Benefits

  • Water-Cooled Design
    Allows more efficient heat dissipation, enabling higher amperage welding without overheating. Perfect where long welds, AC/DC TIG work, or high duty cycles are required.

  • Handle Switch (Trigger)
    Switch on the handle allows the operator to start/stop the arc directly, giving more control without relying on foot pedals or machine‑solenoids. Useful for portability, field work, or when the machine lacks built-in switch control.

  • Two Cable Lengths: 4M & 8M

    • 4‑Meter version: lighter, easier to manage, less drag—better suited for bench work or shorter runs.

    • 8‑Meter version: extended reach improves flexibility when welding large or fixed workpieces, or when moving around machinery.

  • High Amperage Ratings / Heavy Duty
    Typical ratings are 350 A DC / 250 A AC with tungsten diameters from about 0.5 mm up to ~4.0 mm. This makes them suitable for thick materials and demanding industrial environments.

  • LH Bullnose & Threaded Water Hose Connections
    The LB (Left-Hand) threads and bullnose design fitting ensure proper matching with water cooling hoses. Provides good sealing under pressure and reduces chance of leak or cross-thread issues. Confirm that hose end and inlet are LH threads.

  • Consumable & Parts Compatibility
    Uses standard WP‑18 (and often WP‑17/18/26) consumables: collets, collet bodies, cups/nozzles, back caps etc. Multiple nozzle sizes and gas lenses are often available.
