This Superior Tig 251 DC HF/LIFT VRD welding machine model features Utility Thinspot for fast and precise spot welding , but also MMA adjustments such as Arc Force and Hot Start , and is also equipped with an Anti-Stick and VRD device.

The welding machine is predisposed for remote control and GRA cooling unit and is complete with accessories for TIG welding .

TYPES OF WELDING POSSIBLE WITH Telwin Superior Tig 251 DC HF/LIFT VRD

• MMA : also called coated electrode welding, it is certainly the most widespread welding method in non-professional environments or in processes that do not require particular qualitative and productive performance. This type of welding machines are simpler to use even if they give less precise results from an aesthetic point of view compared to other types of welding.
• TIG : TIG welding requires a lower voltage and therefore absorbs less, it becomes cheaper and is aesthetically the most beautiful. TIG welding has a so-called coin shape due to the circular shapes it produces and is more resistant therefore it is usually used in visible elements and on processes that require precision.
