Switching speed, the time the filter takes to darken once it detects an arc, is worth checking against how you actually work rather than assuming faster is always better for every budget. For most general fabrication and repair work, a mid-range auto-darkening helmet with a sensible shade range covers the vast majority of jobs comfortably.
Portability and power supply matter as much as the process itself. A stick welder will run from a generator or a domestic supply in places a gas bottle can't easily follow, while MIG and TIG set-ups need a gas cylinder and, for anything beyond light-gauge work, a heavier electrical supply. Workshop layout, the materials you weld most often, and how frequently the machine needs to travel are all worth weighing up before settling on one process.
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

Space and power supply are the other two practical constraints worth checking early. Confirming that a chosen machine will run comfortably from the electrical supply actually available in the workshop, and that there's room to work safely around it with materials laid out, avoids the common mistake of buying a machine that then can't be used the way it was intended.
Most people buying their first welder get stuck at the same fork in the road: MIG, TIG or MMA. Each process strikes an arc differently and suits a different type of work, so the right choice depends more on what you'll be building than on which machine looks the most impressive on a shelf.
Most domestic UK properties are supplied with single-phase power, typically 230V, which is more than adequate for light-duty inverter welders used for hobby work, repairs and general fabrication. Three-phase supply, commonly 400V to 415V across three live conductors, is standard in industrial premises and delivers power more efficiently to heavier equipment, which is why higher-output welders and plasma cutters, including some Fronius and ESAB machines, are often offered in a three-phase version.
