1.2. Volt-Ampere Characteristic
SMART 200 TIG PULSE welding machine has an excellent volt-ampere characteristic, whose graph is shown as the
following figure. The relation between the conventional rated loading voltage U2 and the conventional welding
current I2 is as follows:
When I2≤600A，U2=10+0.04I2(V); When I2¬＞600A,U2=34(V).
