Every product is backed by our Fit Guarantee. If a part is incompatible with your machine, you can return it hassle-free. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will arrange collection. For other returns, email us first to obtain a Return Merchandise Number before sending. Returns are accepted within 30 days of purchase, in original packaging, on UK orders. A restocking fee may apply on returns where the buyer has changed their mind. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and "Check where we deliver" confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.

The two main variables are gas type and cylinder connection thread. Argon and argon-CO2 mix cylinders (used for MIG and TIG) take a different regulator to a pure CO2 cylinder, so confirm your gas first. Most UK industrial cylinders use a W21.8 bull-nose connection. Disposable and hobbyist bottles use a smaller proprietary thread, so you need a regulator listed specifically for that bottle type. Check the cylinder collar or your gas supplier's documentation if you are unsure which connection you have.

No. Argon and argon-CO2 mix regulators use a different internal seat and outlet thread to pure CO2 regulators. Fitting the wrong type can result in a poor seal, inaccurate flow readings, or regulator damage over time. If your process switches between gas types, you need a separate regulator for each. Argon-CO2 mixed gas (such as a 75/25 or 80/20 blend) uses the same style of regulator as pure argon, not the CO2 type.

Typical MIG shielding gas flow runs between 8 and 15 litres per minute, though the correct setting depends on your torch rating, nozzle size, and the ambient conditions in the workshop. A regulator with a dual-gauge display (cylinder pressure plus working pressure or flow) gives you the clearest read. Set flow at the torch end rather than guessing from cylinder pressure alone. If your torch manufacturer specifies a flow range, use that as your reference point.

Trade quantity options vary by product line. Where bulk or multipack pricing applies, this is shown on the individual product listing. If you are sourcing regulators for a fleet of machines or need a quantity not shown, contact the team directly via WhatsApp 07754288583 or email [email protected] and they can confirm availability and pricing for the volume you need.

Fitting the right regulator to a gas cylinder is the step that determines whether a MIG or TIG welder actually runs cleanly, and getting that match wrong wastes gas, disrupts shielding, and puts arc quality at risk. Welding regulators listed on PartsForMachines cover the common gas types used in workshop welding: argon, CO2, and the argon-CO2 mixes that most MIG processes require, alongside regulators sized for disposable bottles of the kind used on compact MIG sets.

Selection comes down to four things: gas type, cylinder connection, flow-rate range, and gauge format. Argon and mixed-gas regulators use a different thread and internal seating to CO2 regulators, so the gas type is the starting filter. Cylinder connection follows, with W21.8 (the standard UK bull-nose fitting) covering most industrial cylinders and the smaller threaded connections found on disposable and hobbyist bottles. Flow rate, typically expressed in litres per minute, should sit within the output band that matches the torch rating and the process in use. One name covers this section, with SIP, Sealey and Draper behind the welding regulators.

A regulator is also a wear item. Diaphragms and seats degrade over time, particularly where CO2 is in regular use, and a regulator showing pressure creep or erratic flow is due for replacement rather than adjustment. Pairing a new regulator check with a hose and torch inspection is a sound workshop habit that avoids chasing gas faults back to the wrong component. Hoses and torch consumables for the same machines are listed nearby in the Welding Consumables and Accessories section.
