A week on, and the somewhat sorry looking chassis has been reinforced. Made good with some decent quality, MIG welding. These were undertaken by a coded, qualified, apprentice-trained weldor. The difference between the good, the bad, and the downright ugly, is immediately obvious.
Penetration and smooth beads are a far cry from the spattery, inconsistent, blobby mess originally presented. A skilled person always makes their trade look effortless. I was always struck by the standard of work possible, even with a basic 90 amp MIG unit. The sort giving change from £240.
However, better quality units can accept industrial (full-sized) bottles, weld aluminium, and other non-ferrous metals, and at higher temperatures, for longer. My needs will never exceed something like this Clarke 230 TEC, which is designed for general repairs and fabrication in automotive workshops/factories.
MIG certainly isn't a magic bullet. There are a lot of jobs/materials it is unsuitable for. Nonetheless, in the right hands, its very versatile.
