Micro-Abrasive Blasting Workstations
Comco Inc. Page 2 Issue Date: July 2016
Operation and Service
The Comco WS2200 and WS6000 series WorkStations are designed for use with all Comco
series micro-abrasive blasters. Each workstation provides a generous work chamber
illuminated by two fluorescent tubes. The work chamber has a large tempered glass viewing
window that is hinged to facilitate loading and unloading of parts. Two 5" arm holes with
flexible rubber iris baffles permit access so that an operator may hold work with one hand
and a nozzle handpiece with the other. The workstation has a 4" dust exhaust connection at
the rear so that a high capacity dust collection unit may be used to keep the abrasive dust
completely controlled.
The Comco WS2200 and WS6000 WorkStations are designed to work as part of a micro-
abrasive blasting system consisting of the following:
1. The workstation
2. Pressurized air (gas)
3. An air filter-dryer
4. A dust collection unit
5. A micro-abrasive blaster (AccuFlo®. MicroBlaster®, PowerFlo®, or DirectFlo™)
Micro-Abrasive Blaster
The micro-abrasive blaster is the heart of the blasting system. The manual that
comes with your blaster will cover in detail the system requirements and operation.
Refer to that manual for more information regarding preparation, set-up, operation
and maintenance of your micro-abrasive blasting system.
Dust Collection Unit
An industrial type dust collector is necessary to provide adequate air flow to
evacuate spent abrasive particles from the workstation. Typically the dust collector
should be capable of providing 350 to 500 scfm of air flow through the workstation. If
the dust collection unit delivers lower volumes of air, it will not be able to remove the
heavier, coarser abrasives and will diminish the operator's visibility in the workstation.
The Comco Warranty
Comco warrants that the workstation will be free from all defects in material and
workmanship under normal use for a period of one year from the date of purchase or 2,000
hours of normal operation, whichever comes first. Contact Comco Inc. for complete details
and exclusions regarding this warranty.

Safety Precautions
The following safety precautions are essential for safe use of the workstation:
1. The workstation operates using high voltage electrical power. It has been designed
to be safe to operate when used properly. Any device that uses electrical power
requires that certain safety precautions be observed to avoid potentially hazardous
situations.
Verify the proper operating voltage on the workstation by checking the
nameplate located on the back of the unit.
Unplug the unit from facility power when removing the back panel, replacing
lamps, or working near the lamp brackets.
Keep the interior of the workstation clean of dust, powder, and any foreign
object or substance that could conduct electricity.
2. The workstation is typically used as part of a complete micro-abrasive blasting
system. A dust collector must be used in conjunction with the workstation.
Always use a vigorous dust extraction device to prevent hanging dust clouds
and minimize the risk of sparks from static electricity.
Flammable powders, such as wheat starch, walnut shell and plastic,
may pose a fire or explosion hazard.
Some powders, if allowed to collect inside the machine, may cause
electrical shorts.
If sensitive to powder or dust on the skin, wear gloves in the workstation.
Workstation Set-Up and Operation
Installation
1. Remove the workstation from its shipping container and place it securely on a solid
workbench or counter so that the unit cannot tilt or fall over. Make sure that the
location where it is to be used is within reach of a power outlet.
2. Place the micro-abrasive blaster on or near the workstation according to the
instructions in the blaster manual.
3. Identify the abrasive tubing leading from the vent pinch on the rear (or side) of the
micro-abrasive blaster (see machine manual). Push the hose (or hoses) into one of
the tubing grips on the back of the workstation. Push 1 to 2 inches of the tubing
through the grip and hand tighten nut to secure tubing.
CAUTION: The workstation weighs approximately 45 to 55 pounds,
depending on the model. Use appropriate caution while lifting.
CAUTION: Failure to secure the free end of the vent hose may allow it to
fall out of the workstation and potentially whip around if left unsecured.
Always secure the free end of the hose.

4. Using a 4" diameter flexible duct and 2 hose clamps (usually provided with the dust
collector), connect the workstation to a dust collection unit.
5. Follow the instructions in your micro-abrasive blaster manual to prepare for blasting.
6. With the Power switch on the rear of the workstation turned to OFF, connect the
power cord to the AC voltage outlet.
7. Turn the Power switch to the ON position. The lamps in the workstation should light.
Operation
1. Micro-abrasive blasting operations should be conducted according to the instructions
in the blaster's operation manual.
2. Turn the Power OFF when the workstation is not in use.
Common Problems, Causes and Solutions
Light won't illuminate
Fluorescent lamps burned out
Powder build-up in lamp bracket,
preventing electrical contact
Ballast failed
Switch failed
Dust builds up inside
1. Remove old lamps
2. Replace lamps (commercial items)
1. Unplug unit
2. Remove lamps
3. Use brush to clean out bracket
4. Reinstall lamps
5. Plug in unit and test
1. Remove lamps
2. Turn Power switch to ON
3. Using voltmeter, test for voltage
across lamp bracket terminals
CAUTION: Practice electrical safety to
prevent shock.
1. Unplug unit
2. Remove back panel
3. Using ohmmeter, test for continuity
across switch terminals with the switch
set to ON.
Service dust collector
CAUTION: The air that comes out of the nozzle contains abrasive. Do
not point the nozzle at anything that could be harmed or damaged as a
result of abrasive flow.
CAUTION: Never point the nozzle in the direction of the glass window.
The abrasive stream will etch the glass, reducing operator visibility and
requiring premature replacement of the workstation window.
