How to set up a welding workshop at home

When it comes to DIY, I’m all about organisation. Anything that can make my life easier so when I come to start a new project, I have everything I need.

Now I am not a welder (that’s my husband). But we have a setup that’s working well for us in the garage, so I figured, let’s tell you about it.

MIG (Metal Inert Gas) welding is the most beginner-friendly type, and has become really accessible for home DIY, from custom garden gates to steel shelving units. And the best news is you don’t need a sprawling workshop or a six-figure budget to get started. So here’s how you can set up your very on welding station at home on a budget.

 

Step 1: Choose your workspace

Start by identifying a corner or section of your garage that you can dedicate to welding. You’ll want at least 4×4 feet to move around comfortably and 6×6 feet is even better.

The area you choose should be away from any windows and doors, as well as anything that’s potentially flammable. You’ll also need to check that your power supply can handle a MIG welder. Most home units need a dedicated 20-amp circuit (some may even need 30-amp), so have a look at your consumer unit (fuse box) before you buy anything.

Once you’ve chosen your space, clear out anything that doesn’t belong, particularly paint cans, fuel, propane bottles and anything combustible. Welding sparks travel further than you’d expect, and you really only need one to ruin your day (and possibly your garage).

 

Step 2: Plan your ventilation

This is non-negotiable, so it’s worth getting your head around before anything else.

Welding fume is genuinely hazardous. The HSE (Health and Safety Executive) reclassified it as a Group 1 carcinogen in 2019, meaning there’s no known safe level of exposure. Simply opening a window or pointing a fan at yourself doesn’t meet the standard.

For regular indoor welding, you’ll need a dedicated Local Exhaust Ventilation (LEV) fume extractor, a mobile unit that draws fumes away from the source. A decent one costs around £100 to £300. If you’re only welding occasionally (less than once a week, under an hour at a time), good general ventilation plus an appropriate respirator (minimum FFP3 rating) may be enough, but a fan alone simply doesn’t cut it.

Welding with the garage doors open helps, but even outdoors, the HSE is clear that you still need a proper welding respirator instead of just fresh air.

 

Step 3: Set up your welding table

You need a good, sturdy work station to put your welder on. It needs to be stable and non-flammable, and ideally metal, since a metal surface can also act as the earth (ground) connection for your welder, which makes setup simpler. 

If you’re using a gas bottle, make sure you leave enough space for it somewhere around the work station. Some budget MIG welders use “flux-core” wire and don’t need external gas, but gas-assisted welding gives cleaner results. If you go the gas route, you’ll need a 10-litre or 20-litre argon/CO2 bottle.

 

Step 4: Choose your welder

This is where budgeting comes in. A basic MIG welder for hobby use typically costs £300 to £600, but there are lots of variations and choices available.

You can use my handy table below to match the amps you need to the type of welding you’re going to be doing. The project you’re working on will change the type of welder you need, so do your research first.

Most welders will need a dedicated 20-amp circuit, so don’t assume a standard 13-amp plug socket will be enough for anything above 130A.

Material/Project type	Typical thickness	Recommended amperage	Notes
Thin sheet metal	Under 2mm	~90 amps	Suitable for light work, but limited for anything thicker
Decorative steelwork, garden items	2 to 3mm	120 to 140 amps	Provides better penetration and avoids weak welds
General fabrication (mild steel)	3 to 5mm	140 to 180 amps	A good all-round range for workshop use
Structural work, brackets, angle iron	5mm+	150 to 200+ amps	Offers the headroom needed for stronger, consistent welds

 

Step 5: Gather your safety gear

Safety is important, so don’t skip this. Welding burns hurt, eye damage is permanent, and respiratory protection is not optional. Here’s what you need:

• Welding helmet with auto-darkening filter (£80 to £150). The lens darkens automatically when you strike an arc, and it’s worth every penny compared to a manual flip-down.
• Leather welding gloves (£15 to £30). Leather handles the heat and spatter, whereas standard work gloves won’t.
• Welding apron or jacket (£30 to £60). Leather is ideal as it stops sparks, but avoid cotton, which can catch and burn.
• Steel-toed boots (£40 to £80). Your feet will thank you.
• Hearing protection (£10 to £20). MIG welding can regularly exceed 85 dB, which is the level at which hearing damage starts to occur with prolonged exposure. Cheap foam earplugs do the job fine.
• Welding respirator / RPE (£20 to £80). Look for one rated FFP3 or above (that’s the filter grade that traps fine welding particulates). Required outdoors and as a backup to your fume extractor indoors. Don’t buy a basic dust mask and assume it’s enough.

Don’t cheap out on the helmet, gloves, or respirator, as you’re protecting your hands, face, and lungs.

 

Step 6: Stock your consumables

Thre’s nothing worse than running out of supplies mid-project, so check yu have everything you need before you get started. This includes:

• MIG wire: 0.8mm or 0.9mm diameter for mild steel (the most common choice for beginners). A 0.9kg spool costs £8 to £15 and will last you through several small projects
• Shielding gas (if needed): a standard argon/CO2 mix, sometimes labelled “C25” or “MIG mix.” A 10-litre bottle costs around £40 to £60 to fill and will easily last through dozens of small projects
• Contact tips and nozzles: these wear out quickly and are only £2 to £5 each. Keep a handful of spares.

 

Step 7: Plan your first projects

Before you start doing anything, you need to get to know your welder. And no, I don’t mean take it out for dinner and drinks. You need to get to know the feel of it and how to work it, so pick up some scrap steel offcuts from a local steel stockholder (often free or very cheap) and practise your joins before you tackle anything real.

A simple shelf bracket, a garden sign stand, or a small bench frame is a perfect first project, useful, satisfying, and teaches you the fundamentals without the pressure of it mattering too much.

 

Step 8: Weld away

Once your workshop is up and running, you’ll be amazed at what becomes possible: garden shelving, plant stands, fire pit grates, railings, and more. There’s something genuinely satisfying about making things from steel you’ve fused together with your own hands.

If you’re at the stage of choosing your first welder and not sure where to start, TEC Products can help you figure out what makes sense for your projects and budget. Whether you’re building something functional or purely decorative, having the right machine from the start makes the whole learning experience a lot more enjoyable.
