The Micro Welder Experts
Screw C adjusts the vertical (up/down) positioning of the laser. Turning the screw in a clockwise direction will
raise the weld spot location.
Screw D adjusts the horizontal (left/right) positioning. Turning the screw in a clockwise direction will move
the weld spot location to the right.
Only adjust one screw at a time. Typically, only small adjustments are needed. A quarter turn of the screw will
result in a large change in the weld spot location.
Continue turning these screws until you are able to make the weld spot location fall in line with the crosshairs.
ATTENTION: Always use small adjustments when aligning the crosshairs. Ensure that the test piece you are
welding on stays stationary inside the weld chamber.
CAUTION: Do not completely unscrew either of these adjustment screws.
Periodically Changing the Cooling Water
It is necessary to periodically change the internal refrigerating liquid (deionized water only). The purpose in
changing the water is to avoid the formation of micro alga inside the cooling system that could reduce or block
thermal exchange efficiency.
ATTENTION: It is advisable to change the cooling water at least every two years, and in particular before or after
any periods of heavy usage.
HOW TO REMOVE THE WATER
• Insert the plastic connection equipped with the welder to the lower Female Connector at the bottom of
the rear panel. See Figure 25.1.
• Remove the Red Plug in Upper Connector and let the water drain out.
Figure 25.1. To remove the cooling
water, connect the plastic tube and
connector that came with your welder
to the Female Connector at the
bottom of the rear panel. When you
remove the Red Plug from the Upper
Connector, the water will drain out.
