Buying Your First Welder: A Straightforward Guide for Hobbyist Fabricators
Abrasive discs look interchangeable on a shelf but perform very differently depending on what they’re made from and what they’re used on. Cutting discs are generally thin, designed to slice through material quickly with minimal heat build-up, while grinding discs are thicker and shaped to remove material from a surface or clean up a weld, rather than cut all the way through it.
Duty cycle is one of the most misunderstood figures on a welder’s spec sheet, yet it tells you more about real-world usability than the headline amperage does. It’s expressed as a percentage over a ten-minute period at a given output, so a machine rated at 30% duty cycle at its maximum amperage can run for three minutes out of every ten at that setting before it needs to rest and cool.
Our own TP Weld Tables range is designed and manufactured in-house in Yorkshire, cut on a fibre laser for tight tolerances, which is the kind of detail worth asking about wherever you’re sourcing a table, and you can see the full range via welding tables.
Budget for a first machine is rarely just the welder itself. A gas cylinder and regulator for MIG or TIG, a decent auto-darkening helmet, gloves and basic workshop ventilation all add to the real cost of getting started, and skimping on the supporting equipment tends to cost more in frustration than it saves in cash. It’s worth pricing the whole set-up before settling on a machine at the top of the budget.
Buying a first welder is easy to overthink. Rather than starting from a shortlist of machines, it helps to start from the work: what materials, what thickness, and how much of it will be done indoors versus outside or on-site. That single question narrows the choice between MIG, TIG and MMA far more usefully than comparing spec sheets in isolation, whether you end up looking at a Jasic entry-level MIG package or something further up the range.
The practical difference comes down to what a machine can draw and sustain. A single-phase supply has a ceiling on how much continuous power it can deliver before tripping breakers or overloading domestic wiring, which is why the highest-output welding and cutting equipment is frequently three-phase only, or offers noticeably better duty cycle performance when run on three-phase. For workshops without an existing three-phase supply, bringing one in usually means an electrician and, in some cases, an application to the local distribution network operator.
