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 recom-
mended 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.
