STEALTH DIGI-TIG 180 DC PULSE PFC MV
SUMMARY
8
control technology to insure current output stably. Meanwhile, the welding current parameter can be
adjusted continuously and steplessly to meet with the requirements of welding craft.
§2.4 Volt-Ampere Characteristic
TIG DC PULSE PFC MV welding machine has an excellent volt-ampere characteristic, whose
graph is shown as the following figure. The relation between the conventional rated loading voltage U
2
and the conventional welding current I
2
is as follows:
When I
2
≤600A
,
U
2
=10+0.04I
2
(V); When I
2
>
600A,U
2
=34(V).
