Re: SLU-70 Lugs
I've tried every iron and soldering gun I have to solder Anderson Contacts onto 6 ga wire and I just cannot get it anywhere near hot enough. The best thing that I've found is a small butane pencil torch, but mine broke so now I use the big propane torch. It gets hot enough but it is a real pain because the flame is so large.

If you need to solder lugs in the pits, please remember that open flames are forbidden there. |

I have a question, assuming you only screw down the lug, do you get a better connection on more finely stranded wire? Like good welding cable as opposed to the junk battery cable they give us? |

If the solder flows through the wire and joint you have a good solder connection. Someone practiced at soldering will know what good solder flow looks like. I would not try to solder the SLU-70 lugs with a 25 watt iron, however. We use #6 welding cable for our power wiring for its flexibility and high quality rubber insulation. The problem with this cable on the SLU-70 lugs is that the wire is fine enough to work its way through gaps in the clamping mechanism. You can end up with a connection that loosens. Solder the connector after clamping the wire it in order to remove this possibility. I would never use the SLU-70 lugs without soldering them. |

Team 1495 works in a school metal shop and has few electrical tools. Soldering with a 25 watt iron is fairly dangerous, since you have a very hot wire and lug near your hands for about half an hour. However it is possible, so you could do it in a pinch. A micro torch is a better idea and that is what Team 365 is going to use on all the new SLU-70 lugs we had to use after we found out that rule at Pitt. |

Re: SLU-70 Lugs
We over looked that rule as well and this year we thought we're on top of it by soldering all our 6 gauge crimp connections - oh well - we replaced them with the SLU-70 lugs and all was well they held up through 15+ matches. I did notice a couple of rookie teams that had their lug screw pressing onto their wire instead of the screw pressing onto the V shaped clamp and then agaist the wire. Perhaps this might be why some teams had them coming loose.

The electrical rules have changed each year for several years now. You will need to check next year's rules in order to be in compliance for your 2006 robot. |

Re: SLU-70 Lugs
I thought it important to resurrect this thread and remind everyone that although the rules were relaxed for this last weekend (difficulty in obtaining the parts) SLU 70 connectors will be required at nationals. Home Depot, Menards, Lowes, Ace Hardware and of course Terminal Supply are all sources of this connector. Please watch for changes from FIRST, until then, Be Prepared!

Re: SLU-70 Lugs
Our team came in last evening and changed out the connectors on all 9 batteries. Our electrician had done a good job crimping and taping (lots of it) so it took us a lot of time to get the battery plugs off of the battery. Whew!
We also connected those Anderson plugs on all four of our battery chargers to make charging easier, safer and less likely to reverse charge the batteries. Remember...only 9 more days to get this done!! Regards, ChuckB |
