You need to be vary aware of your surroundings, as splash will go everywhere. This is always going to be the case with a flux core or gas-less welding, and the Mightymig90 is no different. Had Sealey not provided the mask, we wouldn’t have been welding at all.Īlso, there’s a lot of splashing. As such, holding the mask with one hand wasn’t ideal. Our only criticism is that we prefer to weld with two hands, using one to steady the welding tip as we go. Rather well in the case of the Mightymig90.ĭuring welding, the Mightymig90 is a doddle to use.

It’s not as efficient as a full-on gas welder, but it works. It’s a flux core wire, in which the core material reacts with the weld/heat, and generates gas. The gas actually comes from the welding wire, which is unique to this kind of welder. So no you’re wondering what the hell a gas-less MIG welder is, right? Well, it is gas-less in the sense that there is no big bottle of gas required (this is good for the home mechanic, as it means the unit takes up less space). With out it, you’ll just get sparks and mess. The gas is fed down the same line as the wire – which ultimately ends with the handheld trigger – and then it’s pushed out over the weld as it happens. In the case of a full-on gas MIG welder, you’ll have the welder and a big old bottle of gas to go with it. If you want a decent weld with deep penetration (snigger) you need gas. There is no such thing as gas-less welding. Whether you have just treated a section of rust or welding the differential, a MIG welder is the easiest and most effective option.First things first, what is gas-less MIG welding?
