Best Arc Welder Overall

The Sealey 150A Supermig is the best arc welder for most home users. It delivers a smooth DC arc that makes welding easier and produces cleaner welds than AC-only machines. With a 150A output and a 20% duty cycle at maximum amperage, it handles 2.5mm to 4mm electrodes comfortably for mild steel repairs, gates, and garden furniture. Owner reviews consistently praise its reliability and build quality. The main limitation is its weight at 12 kg, which is heavier than inverter-based models. Check price on Amazon →

Best Arc Welder for Home Use

For home use, the Clarke 130EN is a solid choice. It is an AC-only arc welder with a 130A output, which is sufficient for most DIY tasks like repairing car body panels, mending fences, or welding thin sheet metal up to 6mm thick. Its duty cycle is 10% at 130A, so you will need to pause between welds, which is fine for intermittent home projects. It is compact and relatively lightweight at 9 kg. The downside is that AC welding can be less forgiving for beginners, but it is a dependable machine. Check price on Amazon →

Best Arc Welder for Beginners

If you are new to welding, the Sealey 150A Supermig is also the best arc welder for beginners because of its DC output. DC welding provides a more stable arc and less spatter, making it easier to learn on. It includes a built-in fan to prevent overheating and has simple controls for amperage adjustment. Many owners report it is forgiving for novices, especially with 2.5mm rods. One honest limitation is that it does not come with a welding helmet or gloves, so factor in those costs.

Best Budget Arc Welder

For those on a tight budget, the Draper 100A Arc Welder is the best budget arc welder. It is a basic AC stick welder with a 100A output, suitable for light welding tasks on thinner metals up to 5mm. It is very affordable and includes a face mask and electrode holder. The duty cycle is only 8% at 100A, so it is not for heavy use, but it is perfect for occasional repairs. The main drawback is that the arc can be less stable than on more expensive DC models, but for the price, it is a capable entry-level machine. Check price on Amazon →

Best Arc Welder for Heavy Use

For thicker metal and more demanding projects, the Sealey 200A Supermig is the best arc welder for heavy use. It offers a 200A DC output and a 25% duty cycle, allowing you to weld 8mm steel and thicker sections without overheating. It handles 3.2mm and 4mm electrodes easily and is ideal for automotive chassis repairs, agricultural equipment, and structural work. Owner reviews highlight its robust construction and consistent arc. The limitation is its higher price and weight of 15 kg, making it less portable. Check price on Amazon →

Best Lightweight / Compact Arc Welder

If portability is key, the Einhell BT-GW 150 is the best lightweight arc welder. It is an inverter-based DC machine weighing only 4.5 kg, making it easy to carry to different job sites. It delivers 150A of welding current and has a 15% duty cycle, which is respectable for its size. It is great for quick repairs on gates, trailers, or garden tools. The downside is that inverter welders can be more sensitive to voltage fluctuations, and some owners report the fan is noisy. Check price on Amazon →

How to Choose a Arc Welder

Amperage Output

The amperage rating determines how thick metal you can weld. For home use, 100A to 150A is enough for up to 6mm steel. For thicker metal, look for 200A machines. DC output is generally better than AC for smoother arcs.

Duty Cycle

Duty cycle indicates how long you can weld before the machine needs to cool down. A 10% duty cycle at 130A means you can weld for 1 minute out of every 10. Higher duty cycles are better for prolonged work.

Electrode Compatibility

Most arc welders accept 2.5mm, 3.2mm, and 4mm rods. Check the manual for recommended sizes. DC welders often work better with rutile electrodes for easier striking.

Weight and Portability

Transformer-based welders are heavier (10-15 kg) but more durable. Inverter welders are lighter (4-6 kg) and more portable but can be less robust. Consider where you will use the machine.

Mistakes to avoid:

  • Buying a welder with too low amperage for your projects.
  • Ignoring duty cycle and overheating the machine.
  • Forgetting to buy a welding helmet, gloves, and rods.
  • Choosing AC only if you need DC for better arc stability.

Arc Welder FAQs

What is the best arc welder for home use?

The Sealey 150A Supermig is widely considered the best for home use due to its DC arc, 150A output, and reliable build.

Is AC or DC arc welding better for beginners?

DC welding is better for beginners because it provides a more stable arc and less spatter, making it easier to learn.

Can I weld 10mm steel with a 100A arc welder?

No, 100A is generally only suitable for steel up to 5mm thick. For 10mm, you need at least 180A to 200A.

What does duty cycle mean on an arc welder?

Duty cycle is the percentage of time you can weld in a 10-minute period. For example, 20% means 2 minutes of welding and 8 minutes of cooling.

Do I need a special power supply for an arc welder?

Most home arc welders run on a standard 13A UK plug, but higher amperage models may require a 16A or 32A supply.

What electrodes should I use for a 150A welder?

For a 150A welder, 2.5mm and 3.2mm rods are ideal. Use rutile electrodes for DC welding for easier arc striking.

How much does a good arc welder cost in the UK?

Prices vary widely, but a decent home-use arc welder typically costs between 100 and 300 pounds.

Is an inverter arc welder better than a transformer one?

Inverter welders are lighter and more portable, while transformer welders are more durable and better for heavy use.

Can I use an arc welder for car bodywork?

Yes, but it is tricky. For thin car panels, use small rods and lower amperage. A MIG welder is often easier for bodywork.

What safety gear do I need for arc welding?

You need a welding helmet with a dark filter, welding gloves, a long-sleeved jacket, and safety boots.

How long does an arc welder last?

With proper care, a quality arc welder can last 10 to 20 years. Keep it clean and store it in a dry place.

Can I weld aluminium with a standard arc welder?

Aluminium is difficult to weld with a standard stick welder. You need special AC/DC machines and aluminium rods, but it is not recommended for beginners.

Our verdict

For most home users, the Sealey 150A Supermig is the best overall arc welder, offering a smooth DC arc and solid build quality. If you are on a strict budget, the Draper 100A Arc Welder provides good value for light DIY repairs.
