The bestarc MIG145 is a 145A multi-process welder — Gas MIG, Gasless Flux Core MIG, Lift TIG and Stick — that runs on 110V or 220V and sells for £171.46. It takes the number 2 spot in this guide on 4.5 stars from 659 ratings, and the listing credits it with a digital display, synergic control and a shoulder strap.

What puts it here is less the number on the box than the numbers that survive the listing. The spec table states "Wattage: 12000 watts" for a machine the title calls a 145A welder — at 240V, 12,000 watts is 50A drawn from the socket, more than a domestic circuit will supply. The weights disagree with each other as well: one bullet says "Weighing only 13.7 lbs", while the spec table lists an item weight of 10.3 kg and product dimensions of 10.27 kg, and 13.7 lbs is about 6.2 kg. Everything on this page comes from the Amazon listing; we have not tested the machine.
