Jack of some trades, Master of none
I have no idea. It's flux cored - I thought it as supposed to be quite messy?
The electrodes are set up for 'no gas'. The wire I am using is also 'no gas'.
It's only known as a messy process because most people in the UK buy a cheap welder without any idea of voltage settings, try it out and write it off as a messy spattery process.
4 things could be the difference between your welds and mine:
1. Polarity. You say you've sorted this, though.
2. Voltage. You need LESS voltage than with solid wire. It WILL spatter if it's too high. You want just enough voltage so it's got a nice spray hiss. You're limited by your machine on this, but try turning it down a setting or two and see what difference it makes.
3. Wire quality. No idea what wire you're using, it will most definitely be the same E71T-11 or E71T-GS wire as the Lincoln, but maybe it doesn't run as nicely.
4. Technique. You need a slight pull angle, not a push, similar angle to stick welding - "If it's slag, we drag" - Bob Moffat. You don't need to do much weaving, just aim the wire into the bottom of the joint and let it do its thing.
