TRANSMIG 350i, 450i, 550i
INTRODUCTION 2-8 Manual 0-5205
As an example, if we were Gouging with an 8mm electrode at 400A, we can see from the graph that we
can expect 400A at 57% duty cycle. For a 3 minute duty cycle period, this means our arc time is 57% of 3
minutes, which is 1 minute & 40 seconds, during the other 1 minute & 20 seconds the machine must be
allowed to cool.
NOTE
Gouging is specified for a 3 minute duty cycle period only.
