Needle hang refers to the distance that the needle extends from the cartridge when the machine is operating. The needle hang affects the pigment flow: if the distance is too long, the needle won’t bring out any pigment as it retracts. The pigment should have an even, consistent flow. If you see either too much or not enough pigment flowing, it is necessary to adjust the needle hang. The needle hang depends on both the length of the needle itself and the length of the stroke of the machine. To find the maximum needle hang for your machine after you insert the cartridge, twist the handpiece until the needle is even with the edge of the plastic tip inside the cartridge. When you turn on the machine, you can see the maximum needle hang. If you extend the needle any longer, again, the pigment flow will be uneven. You can only shorten the needle hang at this point. The pigment should have an even, consistent flow. If you see either too much or not enough pigment flowing, it is necessary to adjust the needle hang or the speed. Shorten the needle hang if there isn’t enough flow and lengthen it if too much pigment is flowing. Adjust the speed of the power supply or the thickness of the pigment. Sometimes, when the flow is insufficient, it is necessary to dilute the pigment with a solution to make it thinner. Pro tip: We recommend that you check the pigment flow on a clean, damp cotton round before touching the skin. Adjust the needle so that the ink flows nicely when you barely touch the cotton round. There should be no spills. If you have tried all of these adjustments and the pigment is still not flowing properly, try another cartridge. There is a small possibility that the box of needles has a manufacturing problem. If this is the case, contact the store since Permabeu will replace the defective needles.
