Frequently Asked Questions
How do I choose between a gas-cooled and a water-cooled TIG torch?
It depends on your welding intensity and duration:
Gas-cooled torches (like TIG 9 and TIG 26) are lightweight and ideal for short to medium-duty tasks such as sheet metal work, repairs, and low-to-medium amperage jobs.
Water-cooled torches (like TIG 24W) are suited for long-duration or high-amperage welding in industrial environments, where 100% duty cycle and sustained thermal control are required. If you’re welding thicker materials or continuously, water-cooled is the better choice.
What size tungsten electrode should I use with each TIG torch?
The electrode size depends on the torch’s rated capacity and the material being welded:
TIG 9: Best suited for small-diameter electrodes (0.5–1.6mm), ideal for thin materials and precise control.
TIG 26: Accepts a wide range of electrodes (0.5–4.0mm), making it versatile for medium-thickness steel, aluminum, and stainless applications.
TIG 24W: Supports 0.5–2.4mm electrodes and is optimized for industrial-grade work like pipe welding, thick plates, and exotic metals.
Why does duty cycle matter when selecting a TIG torch?
The duty cycle defines how long a torch can operate at a specific current without overheating in a 10-minute window. For example:
TIG 9: 35% duty cycle at 120A DC – suitable for short bursts or precision welds.
TIG 26: 35% duty cycle at 180A DC – for moderate-length welds on mid-thickness materials.
TIG 24W: 100% duty cycle at 180A DC – ideal for continuous industrial welding without downtime.
Choosing the right duty cycle prevents overheating, improves performance, and extends torch life.
