The AMP's of power supply

I have been using this cheap power supply at my shop that it seems that it only haves 1.5 AMP. I have been using it for a couple of months because a artist that use to work three just left it behind. And I just finished my apprentice and I was like "Oh what the hell I would use it". And now since I have better machines than before I wonder if my junky power supply would interfere with the performance of my machines. So I am wondering what should I get, a Critical X-2 that haves up to 2.3 AMP or a Sunskin PS300 which haves up to 4AMP? More AMPS is better? Sorry that I am not inform much about the power supply's specs, my so called mentor does not know the difference either since he works in a ghetto shop, and I am trying to get out of it.

Oh wow look...someone who has been apprenticed and is still asking basic questions. Sorry dude, that was not a crack at you, but a shot at the dumb fuck "pros" who think that apprenticing is the cure all. To answer you question, yes, more amps is generally better. I have used a monster point 1.5A and it was junk. The owner of the shop I work at, let me use his back up back up hahaha. It is a heavy older power supply. You will see them for around 100$. Big cream colored power supply. It has a 3A rating. Worked pretty well. But now I am using an Eikon EMS200 while I am waiting for my EMS300 to get here. There is no real difference between the big cream supply and this EMS200, other than the digital readout. I have heard great things from the Critical line. I actually just had that decision to make 2 days ago. I went with an Eikon EMS300. Every convention I have been to, most artist use them and recommend them. Although, I have seen a few pictures of artist/builders like Aaron Cain use the Critical X2. However, I do not know if that is their true power supply when they tattoo, or if it was just to show the reading of a machine. If you are looking to see what the duty is on your machine, you can just buy a multi-meter from Sears for 20$. Hook your machine up to your power supply, turn it to wear you usually run it. Set the multi-meter to "freq" and see what it reads. The closer to 50% duty the better. The reading will be the stress on the back spring. I wish I had more info for you on it. I also wish there was more info about the Critical series power supplies. So best of luck in your search. But the Eikon EMS200 is a great little power supply...and it is fairly inexpensive.

Thanks for the info, that help me out a lot to make up my mind.

You welcome man.

I really don't see why all the extra amperage capability is needed. No machine I have ever used has needed even close to 1 amp of current.
