FAQs

Choose by application. MIG is the workshop default for routine steel fabrication and automotive bodywork (3–10mm steel) — fast, easy to learn, clean welds with shielding gas. TIG is for precision work, thin sheet, stainless steel, and aluminium — slower, harder to master, but the best weld appearance and control. Arc/stick is the rugged choice for outdoor and structural work, farm repair, and conditions where wind disrupts shielding gas — handles thicker sections (6mm and above) easily. Multi-process inverters give all three from one machine, ideal where versatility matters more than maximum performance in any single mode.

For trade and agricultural workshop use, a 180–200A MIG is the sweet spot — enough to weld up to 10mm steel, capable of automotive bodywork at the lower end, with reasonable duty cycle for routine repair work. A 250A machine extends to 12mm-plus structural work. Duty cycle ratings (e.g. 30% at 180A) indicate how long the machine can run at a given output before needing to cool — 30–40% duty at maximum output is normal for trade machines. For sustained production welding, choose a machine with higher duty cycle even if peak amperage is similar.

Smaller welders (up to 160A MIG, smaller TIG and arc) run on 230V single-phase domestic supply. Mid-range trade machines (180–250A) typically also run on 230V but draw enough current that a dedicated 32A circuit is recommended. Larger industrial welders (300A and above) and high-duty-cycle production machines run on 400V three-phase. 110V site-supply welders exist for construction-site use where 230V isn't permitted. Confirm the input voltage on the welder data plate against your workshop supply before ordering.

Parts For Machines is an Authorised Distributor and Seller of Sealey, SIP, and Clarke across welding machines. Sealey leads with the broadest range — from hobbyist welders through industrial inverters, covering MIG, TIG, arc, multi-process, and plasma cutting. SIP covers a similar breadth with the IDEAL, MIGMATE, and TIG-TURBO ranges popular across UK trade workshops, plus the SIP Spot welder range for bodywork. Clarke covers entry-trade and mid-range machines. Welding consumables and accessories — wires, electrodes, regulators, torches — are supplied across all major brands.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. 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.

Welding Machines

Welding Machines cover the wide selection of welding equipment used in plant repair, agricultural fabrication, automotive bodywork, and general workshop use — MIG welders, TIG welders, arc/stick welders, multi-process inverters, plasma cutters, and spot welders. Parts For Machines supplies welders and welding accessories for trade and professional use, from entry-level hobbyist machines through to industrial three-phase inverters. Within Welding Machines you will find MIG Welders (the workshop default for steel and aluminium with shielding gas), Arc Welders and Stick Welders (the traditional all-rounder for outdoor and structural work), TIG Welders (precision welding for stainless steel, aluminium, and thin sheet), Plasma Cutters (high-speed metal cutting), Spot Welders (sheet-metal joining for bodywork), and Multiple Combinations (multi-process inverters that handle MIG, TIG, and stick from a single machine). Parts For Machines is an Authorised Distributor and Seller of Sealey, SIP, and Clarke across welding machines. Sealey leads with the broadest range — covering hobbyist through industrial machines, MIG, TIG, arc, and multi-process formats. SIP covers a similar breadth with the SIP IDEAL, MIGMATE, and TIG-TURBO ranges popular across UK trade workshops. Clarke covers entry-trade and mid-range welding machines. Welding selection comes down to the application: MIG is the workshop default for routine steel work and bodywork (3–10mm steel typically); TIG is for precision work where weld appearance matters or where stainless and aluminium are required; arc/stick is the choice for structural work, agricultural repair, and outdoor use where wind would disrupt shielding gas. Multi-process inverters trade some specialist performance for the convenience of one machine across all three. Product pages list output amperage, duty cycle (typically 30–60% at maximum output for trade machines), input voltage (110V site, 230V single-phase, or 400V three-phase), and supported wire and electrode sizes. Welding consumables — wires, electrodes, gas regulators, torches, gloves, helmets, clamps — are sold under Welding Consumables Accessories.
