MMA, TIG or MIG? Choosing the right process for your work

Grand Welding Solutions LLC · November 2026

Most welding jobs in a UAE workshop can be done with more than one process. The best choice depends on the material, its thickness, where you weld, how much you weld and who welds. Here is how we think about it when a customer asks us for a machine.

MMA (stick) – robust and portable

Manual metal arc welding uses a coated electrode and needs no shielding gas. That makes it the process for site work, wind, structural steel, maintenance and repair. A modern IGBT inverter such as the APS Discover or Genesis range is light, starts easily and runs long cables. The trade-off: slag to remove and lower deposition than wire processes.

TIG – clean and precise

TIG gives the highest-quality, cleanest welds on stainless steel, thin sheet, pipe root passes and non-ferrous metals. It is slower and needs a skilled welder and argon. Pulse TIG (for example APS Genesis PulseTIG) controls heat input on thin and heat-sensitive material; high-current machines such as Genesis 600HD handle heavy sections.

MIG/MAG – productive

Wire processes deposit metal fast and continuously, ideal for production, fabrication shops and long seams. CC/CV machines such as the APS Magnus series also run flux-cored wire (FCAW) – useful outdoors and on thicker structural parts – and can weld MMA from the same power source.

The questions we ask you

• Which materials and thicknesses, and which welding codes or approvals apply?
• Workshop or site – and how long are the cables to the work?
• Single-phase or three-phase supply, and the generator size on site?
• Hours of welding per day (this decides the duty cycle you need)?
• Do you need pulse, water cooling, a separate wire feeder or a trolley?

With these answers we suggest one or two machines and the right torch, cables and consumables – and we can demonstrate before you buy.
