I moved over to a SG-55A torch very similar if not identical to the SG60 series, the bigger the nozzle hole, the more air flow, the more current you need for Pilot, Hence optima Cut 50 on 8 amps that will be a lower value of resistor still and that unit will have a circuit to switch out the resistors or should have for when the arc has transferred.
If you look at item number 162616612458 on Ebay (OK in the UK) you will see a cut 50 supplied with Pilot arc and an SG55 style torch for sale at £195 UKP. Non Pilot arc machines supplied with a PT31 torch (which i think is the cheapest going) for £145. So I wonder why not save a bit more and buy the one that is an extra £50, it saves you buying resistors for a Pilot arc mod trying to make the external fitting to connect to the nozzle (see later videos as I had to midify it to allow air flow past it to help cool and clear dros) and then later also buying another torch.
I did it to mine because when I bought it there were no pilot arc Plasma that were less then £500 back in 2014.
I know you are going hobby, but if you are trying to get make some money, I do not want you to think later if only I had bought a slightly better machine in the first place rather than mess around with bits of resistors! You could potentially spend more maney in the long term.

The cutter which I would like to buy is more expensive than cut 50 , and is better designed , better duty cycle, have the gouging mode ,only needs this mod for pilot arc .
Now I check for a cut 50 whit pilot arc on ebae UK but I always had to replace many things ,the torch because is a kind of toy ,the ground clamp and the ground lead .
Otherwise the hardware itself is cheaper but I think they have no warranty and can't be used with a generator set ,than I did see the photos of the internals and is pourly designed ,power resistor in contact with capacitor or cables
Now Im going to check
