Sell Your Used Welder — 0% Fees

A used welder typically sells for £60 to £400, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Welders sell on process and duty cycle, and the practical detail that decides usability is the power supply — many need more than a standard socket can give.

The short version

Typical range: £60 – £400 — see the full welder value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Note the process it does — MIG, TIG, stick or multi — and its maximum amperage and duty cycle.
Check the power requirement, since larger machines need a dedicated supply rather than a standard plug.
Check the torch, earth clamp and leads for damage, and note whether a gas regulator is included.

The photographs that sell a welder

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The torch, earth clamp and leads laid out
Any consumables or regulator included, plus any damage

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Process, amperage and supply: “MIG Welder, 180A, Gasless and Gas, 240V”. Process is the first filter and amperage the second. Say the supply requirement plainly — a machine needing a 16A or three-phase supply is unusable to most home buyers.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Welding process or processes, and maximum amperage
Duty cycle at a stated amperage
Power supply required, and whether a standard plug is fitted
What is included — torch, earth clamp, regulator, consumables

What buyers will actually ask

You will receive the same three messages about a welder. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“What power supply does it need?”

Read the plate and say. This is the question that decides whether the buyer can use it at home at all, and it is the most common wasted enquiry.

“Is a gas regulator included?”

Say so. Regulators are a real cost and gas cylinders themselves cannot be posted and are usually the supplier’s property.

“What is the duty cycle?”

Quote it with the amperage it applies at. Duty cycle is how long the machine can weld before it needs to cool, and it is what separates hobby machines from serious ones.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The welder value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £230 sale — roughly the middle of the range for a welder — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£230
Poshmark	−£46	£184
eBay	−£31	£199
Mercari	−£23	£207
Etsy	−£15	£215

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Steady year round with a modest spring lift. Multi-process machines and known brands sell within a fortnight to a knowledgeable audience.

Heavy. Never include a gas cylinder in a posted parcel — compressed gas is a dangerous good and cylinders are normally the supplier’s property on an exchange scheme. Collection is usual.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used welder worth?

Typically £60 to £400, with multi-process inverter machines above. See the welder value guide for the condition bands.

Can I include the gas bottle?

Almost never. Cylinders are usually rented or exchange property rather than yours to sell, and compressed gas cannot be posted. Sell the machine and let the buyer arrange their own gas.

Do I need special wiring for a welder?

Larger machines do. Quote the supply requirement from the rating plate so the buyer can check what they have, rather than discovering it after collection.
