2) Fit the toroidal coil onto the welding machine’s arm or secondary conductor.
When fitting the coil, be careful with the following:
•
Keep the toroidal coil’s hooking bracket as far away from the welding
machine’s arm (secondary conductor) as possible.
•
Do not deform the circular form of the toroidal coil when fitting it.
CAUTION
•
If the toroidal coil is fitted in reverse orientation, the waveforms in the
WAVEFORM screen and the analog output waveforms measured with the
oscilloscope are also shown in reverse.
•
For a band-type toroidal coil, do not deform it when fitting it. Repeated
bending and extension may break internal wires.
Do not deform the circular
form of the toroidal coil.
Keep the hooking bracket at the
furthest point from the arm.
