WARNING: This product, when used for soldering and similar applications, produces chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.
PLEASE
Before using your new Weller
® Microtouch MT1500LL unit, read this manual thoroughly. In only a few
minutes you will become familiar with your new station and be able to get the soldering performance you’re
entitled to. Be sure to keep this manual in a handy place near the unit for reference.
SETTING INPUT POWER
This soldering station can operate on 120 VAC or 230 VAC at *50/60 Hz. The fuse holder located under the
power cord receptacle on the back of the station also functions as a voltage selector.
Before plugging the power cord into its receptacle, be sure that the proper voltage has been selected. If
not, pull the fuse holder out of the station and line up the arrow next to the desired voltage with the arrow
located in the lower right hand corner of the receptacle housing. See figures on right. Push the fuseholder
back into its socket and press until the holder face is flush with the housing.
THE FUSE HOLDER MUST BE POSITIONED FOR THE CORRECT VOLTAGE RATING OR DAMAGE TO THE
STATION COULD OCCUR.
IF THE FUSES NEED TO BE REPLACED FOR ANY REASON, DO NOT SUBSTITUTE DIFFERENT RATED
FUSHES. The two fuses installed are different. The arrows on the fuseholder points toward the fuse used
for that voltage. The 120VAC fuse is a 3 amp time delay fuse (Bussmann ® MDQ-3) and the 230VAC fuse is a
1 amp time delay fuse (Bussmann ® GDC-1 or S504-1).
Insert universal end of line cord into the receptacle located on the back of the power unit, and insert the plug
end into a properly grounded AC receptacle.
THE MT1500L STATION IS EQUIPPED WITH AN INTERNAL AUTOMATIC RESETTING FUSE.
If the handle or tip were to short out, the fuse would heat up and switch off heater power. The
display and indicators would still light up but the heater power would stay off until the problem is
fixed and the station turned off for a few minutes to allow the fuse to cool. This fuse will also
switch off if an MT200 series tip is overworked.
INTIAL SET-UP
Unpack the unit carefully. Assemble tool stand as shown in the figure at right. Fill reservoir with
water and wet sponge. Distilled water is preferred. Install the desired tip (TIPS NOT INCLUED
WITH STATION, SEE TIP SHEET FOR STYLES AVAILABLE) into the receptacle end of the
handpiece until it is well seated. Insert tool into holder and connect tool plug to receptacle located
on the left front panel of power unit; rotate plug cover to lock plug into place.
Choose a mode of operation with the mode switch located on the front of the power unit (see
Modes of Operation). Temperature “keys” for 600°F (315°C), 700°F (371°C), and 800°F (427°C)
are included with the MT1500LL station. Select a temperature “key” for the soldering tip tempera-
ture desired and plug into socket located on the right side of the front panel. If the desired
temperature “key” is not installed, the “key” may be changed while power is on. Turn the station
on with the power switch located on the back of the unit. When the red “Tool Ready” LED on
the front panel lights, the tip is at temperature and is ready to use.
MODES OF OPERATION
TOUCH MODE
The Touch Mode is primarily intended for soldering very small components with microtips and to extended tip life with larger tips. In Touch Mode,
the tip is heated only when the touch ring located at the front of the handpiece and the metallic portion of the rear of the handpiece are both
touched by the operator’s hand. When contact is broken, power is turned off to the heater and the tip will cool to ambient temperature. The Touch
Mode will maximize tip life by preventing the tip from sitting at high temperature for extended periods of time. Occasionally, dry hand will cause the
Touch Mode to malfunction. In this situation, the use of a moisturizing hand lotion is recommended.
IDLE MODE
The Idle Mode operates similar to the Touch Mode; however, it incorporates a delay before cooling to 400°F. When contact is broken, after
approximately a 1 minute delay, the tip will cool to 400°F (204°C). Idle Model operation allows larger tips to heat back to the desired temperature
faster. It can also be used in place of the Touch Mode, if desired.
CONTINUOUS MODE
In the Continuous Mode the tip will remain heated to the selected temperature as long as the unit is operating. Continuous Mode is suited for very
large surface mount style tips. This mode of operation may reduce tip life.
