It is heat that melts metal to get sufficient heat you need a combination of current (amps) and time, moving the tourch slower means that the peice of
metal is heated up more for the smae amount of amps used.
Its best to have the tourch moving at a steady continuos speed and set current on the welder to suit.
Unfortunaty to fully explain MIG welding on a forum like this it would take several pages. If you can do plenty of practice welding with an
experianced welder checking how your getting on every so often.
Finding the experianced welder to guide you is the tricky bit, college cources are v.good for that.

If these are unavailable to you, practice LOTS, and experiment with various setting, even ones which you know will give odd results
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Shame you bought a MIG, real men use stick.

I may have lost b*lls in a freak accident at some stage and not noticed, but having done a lot with stick, i'm glad of the change to MIG.
Sticks good at rough and ready gluing of 2 lumps of steel together, but for delicate stuff like 16swg MIG is far nicer. I've tried using stick
on 16swg and didn't bothe continuig any further.

Fairly irrelevant anyway as we can't really use mig where we work.

Phylis Stein!! MMA is the finest of welds, far more control, beautiful flat, even, herringboned welds. Substantially stronger for the mass of
deposited material.
Try 6013 Satinex rods from BOC, you will change your mind!

I'm sure I would be less of a Phylis Stein, if I had done more stick welding with an oxford before it died and some dry rods.
Most of my memories of stick involve getting v.annoyed trying to start a weld when all it did was fix the rod to the work peice, so its probably not
surprising I prefer MIG.

How do the satinex rods compare to BOC everday rods?
I expect being a cheap scate hasn't helped matters.

Apart from being green, they give a very smooth arc, easy striking and a very clean weld. You can use them with 48OCV, but better with 70+
