Solder Reels

11 June 2014 - Further Update - in addition to the issues mentioned below, we have now had deliveries recently and the prices have gone through the roof. It has therefore been necessary to increase the costs of all reels to reflect these changes. As an example, we are now paying considerbaly more for each reel than the price that we have been selling them for. Clearly that can not continue hence the price increases.


With industry hardly using solder wire anymore, it gets more and more difficult to obtain supplies in wire form. It is now almost a case of buying what we can get hold of, rather than ordering specific solders that we would like to buy.

Please bear in mind that there are likely to be changes within our range of solders as we can only sell what we can track down to buy! In may cases this ends up being an 'end of run' from another purchaser and so the amounts available vary greatly from week to week, resulting in a difficult position for us in that we never know if we will be able to purchase some now or in the future. It's a case of pot luck as to what is available at the time. 

Further more because wire solder is not generally made, its price goes up and up to those that do still want it. It is likely therefore that prices will have to rise in the near future.











Lead free

Tin/Silver aids wetting & flow. (runs better)

Better than Tin/Copper

Standard Lead Free for modellers






Low Temp (Red card)

Use – assembly of W/Metal castings, especially if gaps   (* see 138 as alternative)

When fused with W/Metal it melts at higher temp.

Not good penetration qualities, therefore W/Metal to tin brass with 138 or 145

Brass – Makes brittle joints due to Antimony reacting with Zinc in the Brass – tinning helps avoid

Use 2 – ballast for models. Melt in hot water and pour void. Expands as cools holding in place






Low melt

(Clear bag)

Compliments 70. 100 creeps better so best for quality castings that have good fit (70 for gap filling)

Can solder W/Metal direct to Brass (unlike 70) therefore no tinning needed

W/Metal is a low temp alloy t/fore possible to undo kit in hot water






(Orange card)

Use – detailing (use with appropriate flux for metals being joined)

Less heat needed t/fore wont effect larger joints.

Smaller iron can be used (good for difficult places to get to



Solder Cream

(Pink card)

Use – Chassis/boilers (138 for detail)

Good for resistance soldering units






Solder Cream

(Green card)

Make up is right (particle size and shape, with good resin flux) t/fore work neater (only min heat applied) very little cleaning up.  Good for resistance soldering units

* W/Metal - Alt to 70 + tinning (some say 70 is weak)

Method - W/Metal to Brass or N/S = Clean both surfaces + mate till good fit.

Smear 138 onto both surfaces with lots of YELLOW flux. Put tip onto Brass adjacent to W/Metal + hold till solder starts to flow. Remove immediately for clean strong joint.

Wax lost castings – test 1st








(Grey card)

Use – Aluminium or Zinc rich alloys i.e. Mazak. Use GREY flux

Ally absorbs lots of heat t/fore use high watt iron

Ally susceptible to corrosion – need to seal all joints within the hour with Electrofix






Sheet Metal

(Sea Green card)

Use – sheet metal and other close fitting joints

Short melting range prevents distortion

Low surface tension means only a small fillet is left along the joint

Flows more readily than less pure common solders

Low antimony content makes it suitable for Brass and N/S, unlike common electrical solders






Solder Paint  (Bottle)

Use – to tin steel. Suspension of 188 solder powder in active flux compound

Method – Clean both surfaces. Apply thin smear to one side. Assemble joint + hold. Heat until solder melts + shows silvery line through black flux residues

‘Hot Tape’ + ‘Solder Mask’ particularly useful with solder paint and creams

Shake jar (flux to top, solder to bottom) + stir






Gap Filling

(Brown card)

Normal grade of Tinman’s solder, but with low antimony content so suitable for Brass (antimony does not like the Zinc in Brass - see 70 degree).

Longer melting range than 188 + higher surface tension, t/fore useful for filling gaps.

Use for chassis as the fillets strengthen the assembly.

Also better at joining solid components together than 188







High melting range – 235 -> 243

Useful when other soldering has to be done nearby later on, as joints made with this will not bubble or undo.

Flows similar to 188

Should not be mixed with other lead solders as it may become brittle.

If necessary, protect with ‘Solder Mask’






(Orange card)

Use - General purpose especially electronics

Has the good qualities of 188 with high temp resin core (in convenient) wire form

Single core promotes faster melting + better spreading

As resin does not burn quickly, it does not clog the joint with carbon deposits, which inhibit flow of solder.

If it stops smoking then the flux is all used. Use ORANGE flux.








Step Kit

(Clear bag)

Stops previous work coming undone by using solder in stages

227 Lead Free – main assembly (ideal for tinning tips as its 99.7% tin)

179 Tin/Lead (with 2% silver added) – Gives superb wetting + flow for sub assemblies

145 (as C1002) – for detailing






High Temp

(0.5kg reel)

Tin/Lead/Silver - ideal for the larger components.

The Silver assists the solder to ‘flow’ easily into joints




Lead Free

(0.5kg reel)

Lead Free – Tin/Copper high melt solder.

Ideal for larger components and for tinning tips of soldering irons.
