A clean, organized workspace reduces hazards. Keep flammable materials away and ensure good ventilation.
Monitor coolant temperature and flow rate (ideal: 5–15 L/min) to optimize performance.
Upgrade equipment when you notice frequent overheating or unstable arcs.
How Water Cooling Works
The water cooling system operates by circulating coolant through small passages inside the torch head. This coolant travels down hoses to an external reservoir and radiator, absorbs heat from the torch, and releases it at the cooler — keeping the torch near room temperature. This allows welders to work longer without worrying about overheating.[1]
Note: The water cooling mechanism not only protects the torch but also helps the operator by reducing heat exposure — meaning more comfort and safety during long welding sessions.
| Component | Function |
|---|---|
| Water-cooled copper plate | Acts as the anode, helping to dissipate heat generated during welding. |
| Pressure tube | Conducts arc pressure to a sensor, enabling measurement and control of the welding arc. |
| Computer / controller | Collects electric signals from the sensor to determine the arc pressure value. |
Benefits Over Air-Cooled Torches
Water-cooled TIG torches are designed for prolonged use without overheating, making them ideal for high-amperage tasks. Air-cooled torches may need cooling pauses during long jobs, slowing work and reducing productivity. Golden Globe's liquid-cooled models, such as the TIG 27, provide a 100% duty cycle at high currents — less downtime and more efficient welding.
When to Use Water-Cooled TIG Torches
| Scenario / Industry | Description |
|---|---|
| High-amperage projects (typically over 200A) | Require effective cooling to maintain stable arc performance. |
| Long continuous welding sessions | Essential for managing heat during extended use. |
| Stationary workshops / fabrication shops | Ideal where a water cooler system can be permanently installed. |
Essential Equipment for Liquid Cooled TIG Torch Setup
Torch and Water Cooler
A liquid cooled TIG torch setup starts with selecting the right torch and water cooler. Golden Globe offers a wide range, such as the TIG 27 for high-amperage jobs and the TIG 9 for lighter tasks. The water cooler pumps coolant through the torch and stabilizes temperature — match your cooler to the torch's duty cycle and amperage range for reliable, long-term performance.[2]
Tip: Always check the duty cycle of both your torch and cooler. A higher duty cycle means the equipment can run longer without stopping for cool-down periods.
Hoses, Fittings, and Connectors
Hoses, fittings, and connectors link the torch to the water cooler and power source. These parts must be durable and leak-proof. Common connector types:
| Connector Type | Description |
|---|---|
| DINSE | Used for connecting welding cables to machines; available in sizes 10–25 and 35–50. |
| Thread Sizes | Common sizes include 3/8 BSP and M16×1.5 for optimal compatibility. |
Power Source and Coolant
A stable power source must match the torch's amperage rating. For coolant, industry standards recommend propylene glycol or ethylene glycol for their wide temperature range. Pure or deionized water offers the best heat conduction but must be non-conductive to prevent electrical hazards.[3]
| Specification | Details |
|---|---|
| Recommended Coolants | Propylene glycol, ethylene glycol |
| Best Heat Conduction | Pure water or deionized water |
| Flow Rate Requirement | 5–15 liters per minute recommended |
Note: Always use the coolant recommended by your torch manufacturer to maintain the warranty and ensure the cooling system works as designed.

Setup Steps for Water-Cooled TIG Torches
Workspace Preparation
Start by clearing clutter and removing flammable materials from the welding zone. Work on a fire-resistant surface. Keep a fire extinguisher within reach. Good ventilation is critical — use a fume extraction system if needed. Secure gas cylinders upright. For full regulatory guidance, refer to OSHA's welding, cutting, and brazing safety standards.[4]
Assembling Components
Lay out all parts from your Golden Globe kit: torch, water cooler, hoses, fittings, connectors, and power cables. Follow kit instructions for the correct assembly order. Common mistakes and solutions:
| Common Mistake | Solution |
|---|---|
| Incorrect torch assembly (collet, tungsten, etc.) | Verify collet grips tungsten tightly and ceramic cup is the correct size for good gas coverage. |
| Neglecting water-cooled system checks | Regularly inspect for leaks or blockages to prevent overheating and torch damage. |
Note: Take your time during assembly. Careful work now prevents problems later.
Connecting Water Lines and Power
Connect water lines from the torch to the water cooler, following the arrows or labels on hoses for correct flow direction. Tighten all fittings securely. Route hoses away from sharp edges and hot surfaces. Attach the power cable to the welding machine — avoid crossing water lines with power cables. Use cable covers to keep everything organized.
Filling and Priming the Cooler
Remove the protective cap from the coolant reservoir and inspect for cracks.
Lift the coolant bottle and invert it onto the cooler probe, ensuring it locks securely.
Dispense short bursts of coolant to prime the lines. Watch for leaks at all connections.
Open both taps one at a time, allowing coolant to flow in short bursts to clear air pockets.
Repeat several short dispenses until pressure equalizes throughout the cooler.
Confirm successful priming: a steady, splash-free stream with no repeated sputtering.
System Testing
| Step | Description |
|---|---|
| Inspect the torch | Look for cracked cups, loose collets, or signs of heat stress in the torch lead. |
| Check tungsten | Confirm it is clean, properly shaped, and uncontaminated. Replace or regrind if needed. |
| Verify gas flow | Examine hoses and fittings for tightness and confirm proper shielding gas coverage. |
| Inspect cooling system | Monitor coolant flow and return temperature; ensure coolant is clean and flow is unrestricted. |
| Check electrical connections | Work clamp and return path must be clean and tight to prevent arc instability. |
| Annual maintenance | Replace worn items and inspect the full cooling loop for leaks and coolant quality. |
