Welker Rotary MachineRegular price $550.00 Sale price $500.00 Save $50.00
The Welker Rotary is a precision-made tattoo machine. Here are a few of the key features:
The internal (rearward) slide cancels out the up and down forces generated by the
front slide and needle movement. This is achieved by matching the mass of the
internal (rearward) slide to the mass of the front assembly (front slide, needle and rubber nipple). Across the whole range of motion regardless of chosen stroke or running speed the internal (rearward) slide and front assembly (front slide, needle and rubber nipple) move in opposite directions of each other at a mechanically matched speed and distance effectively canceling out the hopping action associated with the up and down movement of the needle.
The crank shaft has two journals driving a desmodromic type system.
The crankshaft is supported on one end by the motors internal bearings and the other
end supported by a stainless steel pilot bearing effectively taking the full load of the
forces involved with decelerating , reversing and then accelerating the masses at
140Hz (cycles per second) off the end of the motor shaft and displacing it between the
motor and the pilot bearing effectively eliminating any applicable motor and drive shaft flex.
The crankshaft journals driving the front and rear slides are arranged 180 degrees
opposed to each other giving the crankshaft a natural balance.
THE DUAL-PLANE DIFFERENCE
The Welker Rotary is referred to as being Dual-Plane Balanced.
Our Rotary Dual-Plane Balancing system eliminates the up-and-down shaking
caused by the needle and armature bar often associated with a coil tattoo machine.
Unlike other standard rotary machines, the up-and-down shaking caused by the
movement of the front slide, has been cancelled out by our Dual-Plane design.
On a standard rotary machine, the side-to-side shaking, (the motion that unfortunately draws ink up and out the top of the tube of a rotary machine), is a result of an eccentric cam-type drive system attempting to balance the up-and-down motion. This too, including the leaking ink, has been canceled out by our Dual-Plane design. Therefore, after canceling these effects, we achieve a stable platform of operation with all components working within their optimal range. Not only does this vastly reduce the fatigue experienced by the artist, it also reduces the stress on the motor from shaft flex and various other factors as well.
We encourage our Welker Rotary machines to be run at speeds equal to coil liner
and shader machine speeds. The optimal range of operation is between 9.5 volts
and 10.5 volts for shading and 10.5 volts to 12 volts for lining.
We have found that artists tend to start at lower voltages due to their previous
experiences with rotary machines. Once an artist starts to become familiar with
the Welker Rotary machine, they naturally begin moving toward the normal
operating speeds that coil machines are tuned to perform.
