MODEL MT1500L - MICROTOUCHPLUS-LOC SOLDERING STATION
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 |
Configuration for 110 - 120VAC |
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. |
|
|
Configuration for 220 - 240VAC |
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.

TIP REPLACEMENT
WARNING: To prevent accidental burns, be sure the power is turned off when changing tips and use the tip gripper.
The Weller® Microtouch MT1500LL unit is made for sue with the new Weller® MT200, MT300, MT600, and MT1200 Series Tips only. These tips are fitted with a special “slip-fit” connector that allows quick tip removal and attachment. Only handle the tips by the grip tube, because manipulating the tips while holding other parts of it may damage the tip and/or cause burns.
To remove a tip, begin by turning the unit off. Wait a few seconds for the tip to cool, then using the tip gripper, grasp the tip grip tube and pull straight off the handpiece. The iron stand has four holes located on top for convenient tip storage. To attach a tip, begin by making sure that the unit is off. Grasp the tip grip tube, and push the tip straight on to the handpiece.
TIP GROUNDING
Most of the MT200 Series tips are not grounded. The MT203 Mil-Spec tip has a special lead grounding the tip through the probe handle. All of the MT300, MT600, and MT1200 Series tips are grounded through the probe handle to the MT1500L station case.
TIPS
The different tip styles available are shown on a separate page included with this booklet. Four different series of tips are available for the MT1500LL Station:
MT200 Series Micro Tips |
MT600 Series Macro Tips |
MT300 Series Mini Tips |
MT1200 Series SMD Tips |
CAUTION: The MT200 Series tips are not designed to be bent. If they are bent either by accident or on purpose the tip is damaged and can fail.
NOTE: The MT204 Conical and MT212 Screwdriver tips are non-wetting. They are unplated stainless steel so that solder will not stick to them. This allows them to be used to break solder bridges that may form between closely spaced pads.
CARE AND MAINTENANCE
TIP LIFE
The tips will last longer if you do not use them at high temperature settings for prolonged periods of time. However, you can extend tip life significantly by making full use of the touch and idle modes. Keep the tip lightly coated with solder at all times. Rosin based fluxes are recommended for optimum cleaning of tip surfaces.
MIRCO TOUCH SOLDERING
Since very little heat is stored in the MT200 series tips, the energy needed to heat the solder joint must come form the tip’s heating element. Because the tip senses loading almost instantaneously and can respond with maximum power, a lower tip temperature setting can be used without danger of board or component overheating. The correct technique for Micro Touch Soldering with your MT1500LL is:
1.Tin the micro-tip with solder.
2.Touch the tip lightly to the pad; create a solder bridge with a small amount of additional solder.
3.Wait for solder to flow and wet components, add additional solder as necessary.
4.Remove tip and allow solder to solidify on connection.
This procedure should provide a quality solder joint with no overheating. Use very little pressure when soldering. Excess pressure will not improve the result but will damage the tip by bending it.
