Welders: Spatter w/ flux core wire normal?

No pictures, sorry. I get spatter everywhere when I try to weld with my new wire feed welder, and the welds look like total crapola. They're all bubbly and what not. I know to try to drag the pool, half circular motion, etc. Spatter still goes everywhere.

Could I be using the wrong wire? I know there are different diameters and materials. Some for MIG's - solid wire - and some with a flux core. I'm using what came with the welder (not MIG capable).

Any ideas?

you may need to change the polarity... flux core uses reverse polarity.

ditto.

Flux Core does have more 'splatter' than solid wire, but you should still be able to weld a decent bead.

80 amp ("low") or 90 amp ("high") - cheap welder, I know.



Change polarity? I've heard of that problem, but I didn't think it applied to flux core. So the ground clamp is actually the hot - which means the inverter's backwards? How would I change this?

Maybe I'm just sloppy.

I don't know what kind of rig you are using , so can't tell you how to reverse the polarity on it . With a stick you just switch the leads . I usually get less spatter with lower amperage . There are silicone based sprays that keep the berries from sticking , if that's a problem .

hey man do you have any pictures of your welds? In some cases excess spatter is caused by having to fast of a wire speed for the heat setting.

if you look at where the drive is for the wire (you may have to open an access panel on the side of the machine) you should see were the leads attach, when welding with flux core you want the ground clamp going to the +'ve terminal.
