Looks good. What welder are you using and what are the settings? Trying to set mine up. How do you use the copper that you mentioned earlier on
Thanks

Hi Steve8274,

Using a Clarke 135TE with Stargas Argon, Carbon Dioxide and Oxygen gas mix. I put a big bottle on mine with a regulator with a flow meter on it. CO2 by itself is crap on this welder anyway! 0.6 mm wire feed and on its lowest power setting I have the wire speed nearly at 7. I find the trick is to set up on a bit of scrap and turn your wire speed up until the tip of the wire starts to hit the work piece, then turn it back just enough so as its not hitting anymore and you get that nice bacon sizzle sound. Very important to have sufficient gas flow so if you dont have a reg with a flow meter on it might be worth getting one of these:

The copper is just a peice of copper gas pipe that I have hammered flat at one end. Its just used as a heat sink and the weld wont stick to it so your not building up weld behind the piece. Was only really using this on areas that I was blowing through on or were important to draw heat away from quicker so as not to distort the panel.

 

Also this technique of stitch welding once you are set up properly is vital:

Hope that is of some help. Thanks for your comments.

I'm guessing you're in Ireland if you are getting work done in Tallaght, will it be ready for the IMM next year? Great work by the way

Would those holes in the front subframe act as crumple zones in an accident ? and maybe crumple up where as without them the whole subframe gets pushed into the car interior.

Had a few hours on the GT today, managed to get doorstep cut out and new one clamped in place, had a little practice on some scrap steel and my welding is getting worse so pushed it back in the garage till next week

Loving the lightened sub frame, do you know that each door card weighs 1.2 kgs, so if you ditch them that'll be a 2.4kg saving and no holes to cut ;)
