That's probably doing more harm than good. If you melt the ends together and then immediately install it and put it under tension, the joint will not be as strong and that may lead to failures.

Properly welded polycord should last for years without failure (tons of factories and warehouses use polycord in their conveyor systems), but the only way to properly weld it is to let the welded joint fully cure for 30-60 minutes under zero tension.

If you do polycord right the first time on a FRC robot, you should never have to redo it.
