How to Start a Metal Art and Welding Business From Your Garage

Yard art, metal wall signs, fire pits and custom brackets are popular garage products. Welding also brings real fire, fume and eye hazards, so plan your setup before you plan your product line.

Choosing a welder

Miller Electric’s first-welder buying guide compares the main processes:

• Flux-core: a wire-feed process that needs no shielding gas. It handles wind outdoors and is forgiving on rusty or dirty steel, though it leaves more cleanup.
• MIG: Miller calls it the easiest process to learn. It makes clean welds but needs a gas cylinder and clean metal.
• TIG: the slowest and hardest to master, but precise on thin material. Most beginners learn it later.

As of October 2026, Harbor Freight’s welder listings show a 120V flux-core welder at about $150, 120V MIG machines from about $500 to $600, a dual-voltage 120/240V MIG at about $550 and TIG machines over $1,000. Its plasma cutters, handy for signs and cut-out art, run about $300 to $1,000. Compare brands before buying. Miller also says to budget for a helmet, gloves, a jacket, wire, gas and other consumables.

Power: 120V vs. 240V

Voltage limits what you can build. Miller says one of its MIG machines welds steel up to 3/16 inch on 120V and up to 3/8 inch on 240V. Thick fire pit rings and brackets may call for 240V. Check your machine’s spec sheet for its circuit needs, and have a licensed electrician add any new outlet.

Safety in a garage shop

• Fire: OSHA’s welding standard for workplaces says to move combustibles at least 35 feet from the work where practical. Where you can’t move them, shield them with fire-resistant covers or metal guards. Keep a suitable extinguisher ready, and watch for fire for at least 30 minutes after you finish. Clear out sawdust, rags, gas cans and solvents.
• Fumes: OSHA’s fume fact sheet links welding fume to short-term dizziness and nausea and long-term lung damage. It recommends local exhaust close to the arc, general ventilation and keeping your head out of the plume. Use a respirator when ventilation isn’t enough. Clean paint and coatings off metal first.
• Arc eye and UV: According to CCOHS, a few seconds of arc light can burn your eyes, and the symptoms may not start for several hours. UV can also burn bare skin. Wear a proper welding helmet, gloves and flame-resistant clothing, and use screens to protect anyone nearby.

What to sell and how to price

Start with a few products you can repeat, such as house-number signs, garden stakes, shelf brackets or fire pits. Then add custom work. To price, add up steel, consumables, finish, your hours at a fair rate and a share of overhead. Then check what local and online sellers charge.

Common mistakes

• Buying TIG first and struggling to finish sellable pieces
• Welding next to the car, lawn mower or a wood bench
• Skipping rust prevention, so outdoor pieces rust quickly
• Assuming homeowner’s insurance covers a welding business. It often doesn’t, and zoning and HOA rules vary by city and county, so check locally.
