Adjusting The Microscope Focus
• Twist the knob on the microscope forward and
backward to lower and raise the head. This will allow
you to focus the microscope on the welding stylus.
See Figure 10.1.
•
Place your finger under the welding electrode to
help judge the correct focus location. Focus the
microscope until the texture on the skin of your
finger is clearly visible.
Power Supply Setup
POWER SUPPLY SUPPORT MOUNT BRACKETS
The PA250i Power Supply can either be mounted to a flat
vertical surface (such as a wall or the side of a desk) us-
ing mounting brackets, or rest on a flat horizontal surface.
Keep in mind that the Power Supply will need to be mount-
ed in proximity to the Microscope Arm Assembly.
Mounting Brackets
If you wish to mount the Power Supply to a vertical wall,
attach the mounting brackets only to a structurally sound
vertical support. One mounting bracket should attach to
the top of the Power Supply and one to the bottom.
Attach the lower mounting bracket to the wall first (using
wood screws or other appropriate hardware, not included)
and attach the Power Supply to the lower mounting brack-
et using the two provided screws. Next, attach the upper
mounting bracket to the Power Supply, then attach the
upper mounting bracket to the wall. See Figure 10.2.
Power Supply Setup - Back Panel
All required cables are found in the accessories box.
• Plug the female end of the included power cable
into the 90-250 VAC Power Port.
• Connect the male end of the power cable into AC
power (wall outlet). The PA250i can accept voltages
ranging from 90VAC to 250VAC. (When plugged in
for the first time the Power Button LED will blink a
couple of times and then turn off.)
Figure 10.2. Use the two mounting brackets to attach
the Power Supply to wall or other vertical surface.
