Compare 17 Series air-cooled TIG torches with a gas valve in the torch head to standard models. Learn which setup matches your machine and workflow.
Quick Answer
Choose a 17 Series torch with a gas valve in the torch head if your welding machine lacks a built-in solenoid valve; otherwise, a standard torch without a valve gives you simpler control and fewer failure points.
Why the gas valve location changes your setup
A gas valve in the torch head lets you turn shielding gas on and off manually at the torch, which is necessary when your machine has no solenoid to control gas flow. A standard torch relies on the machine's solenoid, so gas flows only when you trigger the arc. The trade-off is convenience versus simplicity: the valve adds a control point but also another component to maintain.
When a gas valve torch is the practical choice
If you run a basic or older TIG machine without a built-in solenoid, a valved torch is often the only way to control gas without adding external plumbing. It also suits welders who prefer manual gas control for purging or for welding without a foot pedal. However, remember to open and close the valve yourself—leaving it open wastes gas, and forgetting to open it ruins the weld.
When a standard torch is the better fit
With a machine that has a solenoid, a standard torch simplifies your workflow: gas flows automatically when you start the arc, and you never risk forgetting the valve. It also eliminates the valve as a potential leak point. The downside is that you lose the ability to control gas independently of the machine's trigger.
Key Trade-offs
- Gas control: Valved torch: manual control at the torch; standard torch: automatic control via machine solenoid. Decide whether you need independent gas control or prefer automatic operation.
- Machine compatibility: Valved torch is required for machines without a built-in solenoid; standard torch requires a machine with a solenoid. Check your machine's gas control method before ordering.
- Maintenance and risk: Valved torch adds a valve that can wear or leak; standard torch has fewer parts but depends on the machine's solenoid. Consider long-term reliability and your tolerance for manual steps.
Product Facts
- 17 Series (150A) Air-Cooled Torch w/25 Dinse, 5/8"-18 RH Gas Fitting, & Gas Valve in Torch Head: 17 Series (150A) air-cooled torch with 25 Dinse power connection, 5/8"-18 RH gas fitting, and gas valve in the torch head. The 25 Dinse connector fits smaller machines, and the built-in valve gives you manual gas control when your welder lacks a solenoid.
17 Series (150A) Air-Cooled Torch w/25 Dinse, 5/8"-18 RH Gas Fitting, & Gas Valve in Torch Head - 17 Series (150A) Air-Cooled Torch w/35 Dinse Power Connection, 5/8"-18 RH Gas Fitting, & Gas Valve in the Torch Head: 17 Series (150A) air-cooled torch with 35 Dinse (1/2" OD) power connection, 5/8"-18 RH gas fitting, and gas valve in the torch head. The larger 35 Dinse connector suits higher-output machines, while the gas valve provides manual control for machines without a solenoid.
