YC-400TX3
□□□
is a DC TIG welding machine with inverter technology controlled by IGBT.
□
Features
□
Using PWM controlled technology which offers constant welding current and stable welding arc.
□
There is an electric-shock-prevent switch in the printed circuit board, when people welding in the
danger of electric shock, please turn it on that would guard the operator against electric shock.
□
There are also designed many guard functions, which can stop the welding and give off alarm at the
power abnormality or over-duty using or IGBT damage caused by over-current conditions.
□
Range of fluctuant power voltage :
±
10%
□
Application
Widely applied to the petrochemical industry, power plant, construction industry, pipe-line construction and so
on
