ArcoTig HF200P
2.4 Volt-Amperage Characteristic
ArcoTig HF200P 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
