The main problem with old MIG welding wire is dirt or rust makes a poor conductor.
The following trick will reduce this and make welding smoother.
First obtain a a short length of TV coax Old Type or micro phone cable.
Strip out the coax braid 12.5 to 25 mm or 1/2 to 1 inch.
Remove the MIG welding copper tip.
Slide the coax on the wire and into the recess that the screw copper tip came out
When you have established the amount that will fit in easy cut the rest off.
Push the coax down in side and refit the copper Tip.
What this does is to create a multiple connection to the MIG welding wire via the coax.
This is also most helpful in prolonging the life of a worn welding tip.
(with me it is 5 times longer )
Replace the coax as soon as welding starts to stutter.
All the best Trev
PS I live next the Sea, I had to find a cure for corrosion/rust this was one of them.
