OUTPUT CURRENT IN DIFFERENT MODES
The following oscilloscope patterns show the typical output current waveforms of DTG405 units
for various modes of operation. They can be used for comparison with output currents when car-
rying out service work.
1 FOUR STROKE LIFT ARC DC
2 FOUR STROKE HF-IGNITION DC
a: I1=10 % Imax = 40 A b: slope1=20 %
c: I2=100 A d: slope2=50 %
e: I3=10 % I2 = 10 A i: lift arc ignition
a: I1=10 % Imax = 40 A b: slope1=20 %
c: I2=100 A d: slope2=50 %
e: I3=10 % I2 = 10 A
