Miller W-225 Water-Cooled TIG Torch Kit

The Miller W-225 water-cooled TIG torch kit delivers a 225 A maximum current at a 100 percent duty cycle. Its modular design uses 100 percent copper construction for efficient heat transfer. The flexible neck and configurable head options suit precision GTAW work. Electrode capacity spans 0.020 in to 5/32 in.

Sustained Load Behaviour

Water cooling maintains the full 225 A rating continuously at 100 percent duty cycle without thermal derating. Copper components conduct heat away from the head during long seams. The flexible neck retains position under steady amperage. No back cap is included, so the torch body stays compact for extended runs.

Pre-Order Checks

Verify your power source supports 225 A GTAW output and provides a compatible water-cooling circuit. Confirm the coolant flow rate and pressure match the torch requirements. Ensure your consumable inventory covers the 0.020 in to 5/32 in electrode range. Check that the W-225 modular connection fits your existing cable and hose terminations.

Questions about this item

How much water flow and pressure does the 225 A water-cooled torch need to run all day without overheating?

The kit is rated for a 100 percent duty cycle at 225 A, so the water cooler must supply enough flow to maintain that continuous rating; check the cooler specifications for exact flow and pressure requirements.

What power source and water cooler do I already need to operate this W-225 Modular torch kit?

You need a TIG power source capable of 225 A output and a compatible water-cooling system; the torch connects to standard water-cooled TIG machines and coolers that match the W-225 series interface.

Will the flexible neck and modular head fit the consumables and collets I already use on my older W-225 series torch?

Yes, the W-225 Modular design uses the same electrode range of .020 in to 1/8 in and maximum 5/32 in diameter, so existing W-225 series consumables and collets are compatible.
