Beginner’s Guide to Buying a Welder
Not sure which welding machine is right for your workshop, business, or DIY needs? This guide explains the differences between MIG, TIG and ARC welding, and helps you choose the correct machine size.
Frequently Asked Questions
MIG vs TIG vs ARC welding – which one should I use?
MIG is ideal for fast production and thicker materials, MMA (ARC) is great for outdoor and structural work, and TIG offers precise, clean welds for thinner materials and stainless steel. This multi-process machine allows you to switch between methods depending on your project.
What welder is best for home use or DIY?
A 250A single-phase inverter welder like this model is excellent for home workshops, gates, trailers, light structural steel and general repairs, while still running on standard 220–240V power.
What equipment do I need to start welding?
You will need the correct torch or welding cables, earth clamp, welding helmet, gloves, appropriate wire or electrodes, and shielding gas for MIG or TIG applications. Refer to the required accessories section above for compatible items.
Why does my welder trip the power?
Tripping can occur due to insufficient plug rating, long thin extension leads, or incorrect input supply. Ensure you are using the correct circuit rating and heavy-duty extension leads suitable for high-current equipment.
What size welding cable should I use?
For machines up to 250A, 35–50 mm² dinse-compatible welding cables are recommended to ensure safe current transfer and prevent overheating.
What safety precautions should I take when welding?
Always wear a proper welding helmet, gloves, flame-resistant clothing, and ensure adequate ventilation. Keep flammable materials away and never weld in damp conditions.
