Mostly pushing, found it a lot easier, I think I get what yo mean about focusing on the thicker piece but don't get the sucky bit

Welds are fine as they are curtainly not bird poo examples either wind wire feed back a little or up the rate of weld ie go alittle faster, this is MIG welding and the welds will be proud of the surface no matter what.

I am going out a limb here bruce and reckon you might have a crap helmet/ sight glass. Your welds in the corners are good but the stuff on the flats is all over the place. I think your good in the corners because you have two flats at 90 degrees to guide you. Try a lighter glass and weld between two scribe lines as a guide and see how you get on.

Bob, this is the helmet I'm using, I'm pretty sure I've got travel rate and consistency issues but I'm not sure the helmets helping as I'm still struggling with seeing the joint, will give it a try with scribing and chalking as dualist mentioned when I get set up for a next play

Cant do much more now as I've run out of tube, have to go scrounging round the industrial estates

In the meantime I'l get my eyes tested, I should get that up to date regardless.

Those speedy glass things are not brilliant if you have light coming in from behind. I dont get on with them.

You think Its worth a try without the main lights on? The main ceiling lights running down the centre?

I have a £2.99 Ikea (other lamps are available) desk lap above my bench which balances out the 8 strip lights behind me, just be sure that you don't have the filter set too senseative or it goes dark before you've even started.

DoS, do a destructive test or two. Weld a piece of box to the longer tube with just one fillet seam and then flex it until it breaks off.

Thanks Albert, yes I think I need to do some testing like you suggest, also if I can find a small enough amount I'l get some etching solution and do some slicing and checking.

I have a couple of little hobby lights which I've tried and also without the lighting behind me, neither made much difference so hopefully chalking and scribing will help.

I am not knocking the testing but really once you have the hang of it you know in an instant if the weld is any good or not. You should be in a position by the time you start welding the chassis to know if there is penetration or not and that just comes with heaps of practice. You need clear vision of whats going on and plenty of time with the torch in your hand. Judging your first attempts at mig you wont be long Its also a big mistake to just roll stuff around on the bench, as soon as you are happy with that start on some positional stuff. The learning curve begins again with vertical, horizontal and overhead., all of which you will need at some point in the build.
