best mig wire

[Munkul]

I bought my mig in around 2000. It hardly had any use until about 2014. In 2 equally damp warehouses right by the sea. In Wales! Never rusted - just cheap copper coated stuff.

Well you were lucky. Most cheap wire goes rusty in a year or so of living in an unheated workshop.

My 2nd roll has lasted about 6 or 7 years again no problem. One was from machine Mart the other was cheap online. Branded SIP or something. It's obviously the copper coating that does the trick!

A few years ago I bought ESAB Caddy C200i MIG and it came with 1kg of ESAB 12.51 wire on D200 spool. Kept the spool in a central heated flat and in one year it had gotten rust spots all over.
