R1 569,75

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.
