Process comes before everything. MIG feeds wire continuously and is the fastest way to lay a bead. MMA burns a coated stick and works outdoors where wind would blow shielding gas away. Spot welding fuses two sheets between electrodes without filler at all. Three different jobs, three different machines, and the choice is made before any amperage is compared.
Amperage then follows material thickness. The MIG range runs 100A on the Sealey MIGHTYMIG100 up through 150A, 170A, 190A, 210A and 250A, with the SUPERMIG ladder from a 130A mini to 270A. Arc machines sit at 130A, 160A and 180A. Thin sheet burns through at high current; thick section will not fuse at low current, so the range is read against the metal. Draper Storm Force gasless machines run 100A, 120A and 150A with gas and gasless bodies from 160A to 250A above them.
Gas or gasless is the third decision on a MIG machine. Gasless flux-cored wire carries its own shielding and works in a draught, which suits site and outdoor repair. Gas gives a cleaner bead with less spatter and suits bench work. Many machines here run both, which keeps the option open rather than fixing it at purchase. A machine that runs both also lets the same welder move between the bench and the yard without a second purchase.
Duty cycle is the figure that separates occasional from sustained work: it states how much of a ten minute period the machine will weld at rated output before it stops to cool. It is quoted on 25 of the 60 lines. Torch type is stated per machine, Euro and Binzel Euro on the larger Sealey bodies. Anything unresolved goes over WhatsApp on 07754288583. Stud welding and MMA to MIG converters sit on the same leaf for the jobs that fall between the three processes.
