Product Details

TIGEX reducing valve with flow meter tube for shielding gas welding or root gas protection. TIGEX is especially designed for work where a very accurate reading of the gas flow is required.

The regulator is equipped with a built-in preset safety valve. For maximum safety, TIGEX is also equipped with splinter-free flow meter tubes. TIGEX is supplied with a hose base for hoses with 5.0 and 6.3 mm internal diameter.

TIG Regulators FAQs

Practical answers on choosing, setting up and looking after an argon regulator for TIG welding.

What argon flow rate should I set for TIG welding?

There is no single figure. Maker guidance links flow to the welding current and the size of the gas nozzle, so start from the torch or machine maker's chart for your set-up. Smaller nozzles and lower currents need less; larger nozzles and higher currents need more.

Larger gas lens cups can need more again, so follow the torch maker's data where it exists. Run a test weld and adjust. If you are unsure, our team can help you match a regulator range to your torch and work.

Is more gas always better for TIG shielding?

No. Too much flow causes turbulence, which can pull air into the gas stream and contaminate the weld, so turning the flow up is not a cure for poor shielding. Too little flow leaves the weld exposed, which often shows as a dull bead, small holes or crater-like pits, or blue, purple or straw discolouration on stainless steel.

Set the flow for your nozzle size and current, then check for draughts and leaks before changing it again.

Why are my welds contaminated even though the gas is on?

The usual causes are too little flow, too much flow causing turbulence, draughts, and air being drawn in through a leaking joint or damaged hose. Argon also settles in corners, so the flow needed can vary with the joint and with the shelter around it.

Block any breeze, keep the torch over the end of the weld until the gas stops, check every joint between cylinder and torch for leaks, and confirm the flow at the nozzle. Check the consumables and the cleanliness of the metal too, as these also cause porosity.

How accurate is the flow reading at the torch?

The reading at the regulator is a guide rather than a guarantee of what leaves the nozzle. Makers of nozzle-end flow testers note that the actual flow at the torch can differ from the setting, particularly with long gas hoses.

If consistent shielding matters, a flow test device fitted at the nozzle shows the real flow. If it reads much lower than the regulator setting, check for a leak, a kink or a blockage between the regulator and the torch, and follow the torch maker's guidance.
