New automatic (orbital) pipe welding systems from brands such as Swagelok, Arc Machines (AMI) and Polysoude are sold by quotation, without published prices. On the used market, an Arc Machines Model 227 pipe welding power supply with cooler sells for about $12,250 to $20,000, older complete systems appear from about $9,000, and a Chinese orbital pipe welder is listed at $16,000. The weld head, clamps and collets can add thousands more.
What an automatic pipe welding machine is
Automatic pipe welding usually means orbital welding: a power supply and controller drive a weld head that clamps around the pipe or tube and rotates the arc around the joint, producing repeatable welds. Most systems use gas tungsten arc welding (GTAW, or TIG). There are two broad groups:
- Tube welding systems with enclosed heads for small, thin-walled tube, common in pharmaceutical, semiconductor and food plants.
- Pipe welding systems with open heads and wire feed for larger, thicker pipe. The Arc Machines Model 227 is an example: an inverter GTAW power supply and controller for orbital welding that needs filler wire.
Large pipeline welding spreads for oil and gas are a separate class of project equipment and are not covered here.

Asking prices unless stated. Machinio’s used orbital welder listings ranged from $5,600 to $27,500 when checked in November 2026. Manufacturers do not publish new-system prices, so ask for a quotation.
Why the power supply is only part of the cost
A working system needs more than the power supply. Used-equipment sellers list accessories separately, which shows how quickly they add up: a 50-foot ground cable assembly for the Model 227 was listed at $1,094.50 to $1,534.50, a remote pendant at $2,084.50, and a cooling unit alone at $3,150. On top of that you need:
- Weld heads sized for your pipe or tube diameters.
- Collets or clamp inserts for each diameter.
- Tube facing or squaring tools to prepare joint ends, since orbital welding needs square, clean ends.
- Purge equipment and shielding gas for stainless and other alloys.
- Training and weld procedure qualification for your codes and materials.
New, reconditioned or used
- New: quoted by manufacturers and distributors, usually with training, warranty and support. Request quotes from at least two suppliers for the same diameters and materials.
- Reconditioned: dealer-tested units with a warranty, such as the reconditioned Model 227 above with a one-year operational warranty.
- Used as-is: cheapest, but check that the head, cables and software are included and working. One eBay seller notes that power and connector cords are usually not included unless shown.
Low-priced new Chinese systems are available, but check the weld head range, standards compliance, software language and spare-parts support before buying.
Quotation checklist
- Pipe or tube diameter range and wall thickness.
- Materials, and whether filler wire is needed.
- Which weld heads, collets and clamps are included.
- Cooling unit, cables, pendant and data recording or printing.
- Training, procedure development and calibration certificates.
- Warranty, service location and spare-parts lead times.
FAQs
How much does an automatic pipe welding machine cost? New orbital systems are quoted individually. Used and reconditioned Arc Machines Model 227 power supplies sell for about $12,250 to $20,000, before weld heads and tooling.
Is an orbital welder worth it? It suits shops with repeated, code-critical welds on the same diameters. For occasional welding, manual TIG is usually cheaper.
