Old car battery . . . Well , if you think so, no problem. Buy that empty box for $275 BW , do you know what does it do that switch etch /mark ?
It took me five minutes to get this out of my old personal computer and to cut wire I don t need . Read the label..............
I don t mark my knives.......I have try only one time just to see and CHECK what i read on internet ...........This is done with 12V Dc on that small black device on previous picture .No stencil just simple something like Scotch tape ,letter cut by me and salt water ...
I found that urine from my dog is better choice Look , I try to help you to save some money not to praise my self as one smartest in the room .I have several electronic device which can be used for etch/mark .Actually any transformer from AC to DC will work .Even small battery charger for bike ,and is cheap ten times then this empty box ! 12V DC is enough to do job .Say 18 DC , will be only little faster ,thats all ! Changing from etch to mark is simple changing polarity ... +/ -
This small one is 5 - 35 V + have amper reading
This one is more powerful can from 3 to 40 ? I don t remember ...
Natlek- you have to understand that these people giving you a hard time can not understand making an etcher. They have to buy one.
Yet, they want to make knives!
It's hard for them to understand what a DC power supply is, and how it works.
Let them waste their money.
Ocelot-
You'll go far in this business.
