Starting a welding business costs roughly $33,800 to $109,000 for a mobile rig under the planning assumptions below, and a small fabrication shop adds about $25,000 to $140,000 on top of that. Many independent welders start mobile, with a truck, a welding bed, and an engine-driven welder, because it needs no lease and puts them on farms, fleet yards, and repair jobs right away. A shop comes later, when fabrication work outgrows the tailgate.
Delta Capital Group’s current minimums are 6 months in business, $15,000 in monthly revenue, and a 500 credit score, so Delta’s products are aimed at welding businesses that are already operating rather than pre-revenue launches. If your business is young, our guide to business loans for startups under two years old explains what lenders look for at that stage.
Mobile Rig Startup Costs
| Cost item | Planning range used in this breakdown |
| Used 3/4-ton or 1-ton truck | $15,000 to $45,000 |
| Welding bed or skid with storage | $4,000 to $15,000 |
| Engine-driven welder and generator | $5,000 to $15,000 |
| Additional machines (MIG, TIG or multiprocess, plasma cutter) | $2,000 to $8,000 |
| Grinders, clamps, torch set, hand tools and protective gear | $2,000 to $6,000 |
| Certification testing and any licensing | $300 to $2,000 |
| Insurance down payments | $2,000 to $6,000 |
| Website, phone and invoicing software | $500 to $2,000 |
| Operating reserve for gas, consumables and fuel | $3,000 to $10,000 |
| Total | $33,800 to $109,000 |
These are planning assumptions, not quotes. The truck and the engine-driven welder drive the range, and both are commonly used purchases.

How to Start a Mobile Welding Business
A mobile welding business brings the welder to the work: broken trailer hitches, farm and ranch equipment, gates and fences, fleet repairs, railings, and heavy equipment that can’t easily be moved. The engine-driven welder is the core purchase because job sites often lack usable power, and the same machine often powers grinders and lights.
Mobile work is usually billed hourly with a trip charge. Imagine a welder who charges $110 an hour with a $75 trip charge and spends 3.5 hours rebuilding a set of farm gates. The invoice comes to $460. Rod, wire, gas, and grinding discs cost about $35, and fuel about $30, which leaves roughly $395 before the truck payment, insurance, other operating costs, and paying yourself. Rates vary widely by region and by the type of work, so check what established mobile welders near you charge before setting yours.
Adding a Small Fabrication Shop
| Cost item | Planning range used in this breakdown |
| Lease deposit and first two months’ rent | $5,000 to $20,000 |
| Electrical work and ventilation | $3,000 to $25,000 |
| Shop welders (MIG, TIG and stick) | $5,000 to $20,000 |
| Cutting and forming equipment (band saw, plasma table, iron worker, drill press) | $8,000 to $60,000 |
| Welding tables, fixtures and fume extraction | $4,000 to $15,000 |
| Total | $25,000 to $140,000 |
A shop makes sense when you’re turning away fabrication work, such as custom trailers, railings, brackets, and repeat parts for local businesses, or when customers want to drop work off. Electrical service is the cost that surprises people. Larger shop machines often need 240-volt or three-phase power, and bringing it into a leased space can cost more than the machines.
Fire and Fume Safety
Fire is a central safety risk in welding, especially at customer sites. OSHA’s general welding standard calls for a fire watch in some conditions, including appreciable combustible material closer than 35 feet to the work, and where practicable, combustibles should be moved at least 35 feet away or shielded. Many commercial sites also require a hot-work permit. In a shop, plan fume extraction and ventilation for the processes and metals you weld, since coated and stainless metals produce more hazardous fumes, and keep extinguishers and welding screens in place.
Certification and Licensing
Customers and general contractors often ask for proof of skill, and certification is the usual answer. The American Welding Society says its Certified Welder test is strictly performance-based, with no prerequisite courses or certifications required, and that tests are conducted at AWS Accredited Testing Facilities. To keep a certification active, the welder must submit maintenance documentation every six months.
Licensing depends on the work and the location. Some states and cities require a contractor license for structural or building work above a dollar threshold, and structural steel or pressure piping jobs usually come with their own welder qualification requirements. For repair and light fabrication work, a business registration and insurance are often the main requirements, but check with your state before you advertise.
Financing Equipment as You Grow
Welding equipment, trucks, and beds are commonly financed, with the equipment securing the financing. Lenders look at time in business, revenue, and the equipment itself. If your credit took a hit while you were building the business, our guide to equipment financing with bad credit covers how weaker credit can change the terms.
Finance Your Welding Rig or Shop with Delta Capital Group
If your welding business has been operating for at least six months and you’re adding a second rig, a plasma table, or a shop, Delta Capital Group provides equipment financing and working capital to business owners across the country. Equipment financing is structured around the equipment’s useful life. No collateral is required beyond the equipment for most equipment financing. Approvals happen in as little as 24 hours, and 95 percent of approved applicants are funded within 48 hours. Minimum qualifications are 6 months in business, $15,000 in monthly revenue, and a 500 credit score. Apply at deltacapitalgroup.com.
Frequently Asked Questions
Do you need to be certified to start a welding business?
Not always, but it helps you win work. Many customers and contractors ask for certification, and structural or code work typically requires specific welder qualifications. Repair and light fabrication customers often care more about results and references.
How much does a mobile welding rig cost?
Under the planning assumptions in this guide, a mobile rig runs about $33,800 to $109,000, including a used truck, a welding bed, an engine-driven welder, tools, insurance, and a cash reserve. A used truck and welder keep it near the low end.
Can you run a welding business from home?
Some owners do, especially mobile welders who only store the truck at home. Running a shop from a home garage depends on local zoning, electrical capacity, insurance, and neighbors, so check zoning rules before you take drop-off work.
What kind of welding work should a new business focus on?
Start with the work you can do well and find nearby, such as farm and equipment repair, trailer work, gates and railings, or fleet maintenance. Repeat customers matter more than any single high-paying job.
Can I finance welding equipment?
Yes. Welders, plasma tables, beds, and trucks are commonly financed as equipment. Delta publishes minimums of 6 months in business, $15,000 in monthly revenue, and a 500 credit score, subject to underwriting.
