Types of welding possible with Helvi PUMA 298

• MIG : in MIG welding the electrode is made up of a metal wire which is also used as filler material and the unwinding of the spool occurs semi-automatically.
• MMA : also called coated electrode welding, is certainly the most widespread welding method within non-professional environments or in processes that do not require particular quality and production performance. This type of welding machine is simpler to use even if it gives less precise results from an aesthetic point of view compared to other types of welding.
• TIG : Wire welding is very productive as, thanks to the length of the wire, it does not require constant interruptions for replacement and therefore allows you to work with more continuity. MIG, MAG wire welding machines are types of electric arc welding in a gaseous atmosphere while TIG welding uses rods as filler material (held in the operator's hand) and uses argon or helium.
