ECVV Tig 250 are two processes of sticking and argon-arc welding(choose it by function switch).
As sticking, outer characteristics of welding machine are continued current and arc drive controlling. It is constant current characteristics when arc voltage is normal, it makes that welding current will not be changed with arc length. Current will become higher and higher with arc voltage down-slope, when arc voltage is too low, it makes that arc length will return into the normal range (it is arc driving). When arc voltage is too low to support arc, the voltage will downslope immediately in order to protect from splashing which is caused by short circuit. 
Arc welding characteristic is continue current, welding current will not change arc length, so current is very stabilizing. When the electrode circuit is short, the current will declined to 0 automatically in order to protect the tungsten ad workpiece. 


● Advanced ARC/TIG/IGBT/MMA technology, guarantee stable and large power welding work and save 30% energy.
● 2 in 1 Welder. There is a mode switch button on the panel, you can switch the welding mode with one click. can be spot-welded with high frequency. Another mode is MMA traditional manual welding method, easy to operate.
● The built-in MCU chip (Micro Control Unit) makes the current output more stable and continuous.

● Build-in Hot Start & Arc Force. Easy to arc, spatter and post-weld cleanup are almost non-existent.
● Current Digital Display. Current regulation. The current can be adjusted as needed.
● Cooling Fan System. Fast heat dissipation helps to extend service life.
