Finding Deals on Used Welding Equipment on Craigslist and eBay

Welding equipment is one of those categories where the used market works strongly in the buyer's favor. Hobbyists pick up a MIG welder, finish a project or two, and then decide they're not going to weld regularly enough to justify the space. Small fabrication shops close or upgrade. Farmers sell off gear when they retire. The result is a steady stream of quality machines hitting Craigslist and eBay at prices well below retail.

A Lincoln Electric 180 that costs $600 new shows up used for $250-325 regularly. Hobart Handlers - workhorse MIG welders with a loyal following - sell used for half price or better. Miller Syncrowave TIG machines, which retail for thousands, appear on Craigslist from small shops that upgraded. If you're patient and set your alerts right, welding gear is a great category to hunt in.

What Types of Welding Gear Show Up Used

The used welding market breaks into a few main categories:

• MIG welders (GMAW) - The most common type on the used market. Easy to use, popular with hobbyists. Brands like Lincoln, Miller, Hobart, and ESAB dominate. Flux-core capable units show up often since many buyers got them for one project.
• Stick welders (SMAW) - Older technology but bombproof. Lincoln Tombstone buzzboxes from the 1970s and 80s still weld fine and sell for $75-150. Great for farm/ranch use.
• TIG welders (GTAW) - Higher price points new, so deals are more dramatic used. Miller Syncrowave, Lincoln Precision TIG, ESAB Rebel - these show up from shops and hobbyists who got serious, then got overwhelmed.
• Plasma cutters - Hugely useful, often bought on impulse. Hypertherm Powermax units are the gold standard; even a used Powermax 30 or 45 at $400-600 beats most cheaper new units.
• Welding carts, tables, and accessories - Gas cylinders (check if they're owned vs. leased), auto-darkening helmets, wire spools, rod ovens, and clamps all hit the market regularly and are usually solid buys.

What to Search For

On Craigslist, search your local area for these terms - they consistently surface deals that vague searches miss:

• "Lincoln welder" / "Miller welder" / "Hobart welder" - brand-specific searches catch listings where the seller knows what they have
• "welder lot" or "welding equipment" - people clearing a shop or garage often bundle everything
• "MIG welder" and "flux core welder" - catches hobby-level machines sold by first-timers
• "plasma cutter" - Hypertherm is the name to look for; also Thermal Dynamics and ESAB
• "TIG welder" and "stick welder" - smaller markets but dedicated buyers, so sellers sometimes underprice to move fast
• "welding table" - flat steel fabrication tables can cost $500+ new; used ones from shops go for much less

On eBay, the sold listings filter is your best friend. Search any machine model plus "tested working" and look at what actually sold, not just what's listed. Welding equipment that gets listed above market sits forever; sellers who need to move something price it right and it goes fast. Sort by newly listed and check daily - the good stuff doesn't linger.

How to Evaluate a Used Welder

Before you drive out to look at anything, ask the seller these questions over text or email:

• Does it strike an arc? (For MIG: does it feed wire and make a solid weld?)
• When was it last used?
• Is the gun/torch in good shape, or does it need a new liner or tips?
• Is the ground clamp solid?
• For TIG machines: is the torch included? What's the condition of the back cap and collet?
• For plasma cutters: does it fire a pilot arc cleanly? Are consumables (tips, electrodes) included?

When you're there in person, look at the duty cycle rating on the nameplate and compare it to the condition of the machine. A heavy industrial machine that's been run hard will show it - check the fan screen for spatter buildup, look at the cables for wear near the connections, and inspect the wire drive rollers on a MIG for wear grooves. These are all fixable things, but they're negotiating points.

For a quick function test on a MIG: plug it in, set it to a low voltage, and tack a piece of scrap steel. The arc should be clean and consistent, not sputtery or irregular. For a stick welder: strike an arc on any scrap piece. For plasma: trigger it and see if the pilot arc fires without hesitation.

Red Flags to Watch Out For

Not every cheap welder is a good deal. Pass on listings with these warning signs:

• "Powers on but hasn't been tested" - welding machines are simple; if the seller won't test it, there's a reason
• Melted or scorched insulation on the power cable or leads - this means it was run beyond its duty cycle, possibly repeatedly
• No-name Chinese units marketed as "professional" or "industrial" with no model number you can verify - these often have undersized transformers and poor duty cycles
• Plasma cutters missing the torch or with a generic replacement torch - OEM torches for Hypertherm and similar machines are expensive; factor that in
• Welders stored outdoors or in non-weathertight spaces - moisture gets into the transformer and wire drive, causing corrosion that's hard to fix

Seized wire drive rollers, clogged liners, and worn contact tips are all inexpensive fixes. But a machine with a burnt transformer or a failed control board is usually not worth buying unless you can verify exactly what's wrong and source the part cheaply.

Gas Cylinders - Buy or Lease?

One thing that trips up new welding buyers: gas cylinders. When a seller includes a cylinder of C25 (75/25 argon/CO2) or pure argon, find out whether the cylinder is owned outright or on lease from a gas supplier like Airgas, Praxair (now Linde), or a local welding supply.

Owned cylinders can be transferred with the machine - great deal. Leased cylinders are property of the gas company; the seller legally can't sell them to you, and if you try to exchange them, you'll hit a wall. Ask the seller to show you any paperwork on the cylinder. If they can't, assume it's leased and account for the cost of buying or leasing your own cylinder separately.

Empty owned cylinders sell used fairly often and are worth picking up - a standard 80 cf argon cylinder can cost $150-200 new to own; used ones show up for $40-80 on Craigslist regularly.

What's Worth Buying vs. What to Skip

For most hobbyists and small fab shops, a used Lincoln 180 or Hobart Handler 190 is an excellent purchase in the $200-350 range. These machines are built to last, have good parts availability, and handle most common work up to 3/8" steel without complaint.

If you want to weld aluminum or need precise heat control, a used Miller Diversion or Dynasty TIG machine is worth saving up for. These come up from shops that upgraded to larger industrial units. A used Diversion 180 in good shape for $600-800 is a steal compared to the $1,200+ new price.

Plasma cutters are a no-brainer used purchase if the price is right. Even an older Hypertherm Powermax 30 cuts clean circles around cheap new units. The consumables wear out but are readily available and not expensive. A used Powermax 45 or 65 for $400-700 is a serious deal.

Skip: import "professional" welders with no brand recognition and specs that seem too good for the price. The 200-amp inverter welder that costs $89 new from an unknown brand isn't going to serve you well used either. Stick to Lincoln, Miller, Hobart, ESAB, Thermal Dynamics, Hypertherm, and Victor for equipment you can rely on.

Using Alerts to Find the Best Deals

Welding equipment doesn't move as fast as some categories, but the best deals still go quickly - usually to whoever had an alert set. On Craigslist, set up searches for your priority terms and check them daily. On eBay, save your searches and turn on notifications for newly listed items matching your criteria.

LurkMor makes this easier by watching multiple sources at once and alerting you when something new shows up. Set an alert for "Lincoln MIG welder" or "Hypertherm plasma cutter" in your metro area and you'll be the first call when the right machine hits the market. That matters in a category where the good stuff sells in hours, not days.
