Comments
The nozzle stack is taller than the fine cut set, so the shield is higher for this set than for the fine cut set.
The swirl ring is the version with two rows of larger holes. The tapered end of this piece points up into the torch barrel.
The electrodes are interchangeable.
The nozzles usually have the current rating inscribed on them. If there is no inscription, assume a cone-shaped nozzle uses 45 amps.
