Weller D650 - Manual

MODEL D650 INDUSTRIAL SOLDERING GUN
PRODUCT DESCRIPTION
The Weller
® D650 Industrial Soldering Gun is a multipurpose heavy duty tool
boasting the highest power output of the Weller ® soldering gun product line.
The D650 yields 300 watts of power in the high trigger position and 200 watts
in the low trigger position. The D650 features a new thermoplastic housing
and a three wire power cord. Designed for many applications, a selection of
soldering, cutting, and smoothing tips are available for the D650.
OPERATING INSTRUCTIONS
The D650 Industrial Soldering Gun is designed for intermittent use with a duty
cycle of one minute power “On”, then four minutes “Off”. For high wattage
output (300 watts), pull the trigger to the first position. For low wattage output
(200 watts), pull the trigger to the second position, or fully compressed. (See
Figure below).
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.
SOLDERING HINTS
Soldering is a fast and easy way to join metals. Solder has a low temperature
melting point and with heat flows into the joint via capillary action, fusing the
parts together. A properly soldered joint is considered both mechanically stable
and electrically efficient. To correctly solder a joint, you need:
· A source of heat - your Weller ® soldering gun
· Clean metal surfaces to be joined
· A suitable grade of flux cored solder
· Flux - when not using flux core solder
‘Flux-cored’ solder is used for the majority of jobs. ‘Flux-cored’ solder contains
flux in the strand of solder, rendering separate fluxes unnecessary. Rosin core
solders should be used for electrical connections.
Follow these instructions for best results:
1. Assure that items to be soldered are especially clean at the
connection area. This can be achieved with wire wool or fine emery
cloth. Just because a piece of metal looks bright and clean it is not
necessarily so.
2. Make a good mechanical connection by wrapping wires around each
other or around a terminal post.
3. When applying heat, apply a small amount of solder to the tip to
provide proper heat transfer. Heat should be applied to the base
material e.g. wires so that they become sufficiently hot to melt the
solder to flow into the joint.
4. After the solder has flowed, smoothly slide the tip away to leave the
joint neat. When using a soldering gun, the trigger should never be
released before the tip has cleared the solder joint. Allowing the tip to
cool while in contact with the solder will result in a disturbed joint.
5. Avoid joint or wire movement while soldering. A soldering aid tool or
pliers can be used to hold the joint in place. Gently blowing on the
joint will speed cooling.
6. On electrical and particularly electronic components avoid too much
heat. To achieve this use a pair of Xcelite ® long nose pliers between
the solder joint and the component body. They will act as a heat sink
and dissipate heat away from component.
7. Do not apply more solder than necessary. Excess solder may
damage components and cause short circuits.
8. It is advisable to tin wires before soldering, especially stranded wire.
Twist the strands together then heat and saturate with solder.
9. Creating a joint is easy after tinning. Just twist the wires together and
apply a little solder or flux with heat. The result will be a smooth
electrically efficient, soldered joint.
10. To un-solder a joint apply heat and use a soldering aid tool to
separate joint. Be sure to use new solder when re-soldering.
11. Fumes given off by some fluxes can be dangerous. Important: Be
sure there is adequate ventilation to the working area.
