Hi, I'm new to this forum but I'm I'm a long time member on Malcolms Renault 4 website. I'm South African, but have been living in France for the past 10 years. A few years ago I decided to teach myself mig welding and bought a Mig152 welder made by FAR tools. I think it is a 140Amp machine. It came with some 8mm flux cored wire but also has the option to use gas, which I've never used. I've done a few repair jobs at home, (and burnt some holes in some outdoor metal garden furniture) and then I packed it away and decided that I'm not a very good welder. Now I have to do some repair work on my car. I took my door off and gave it to a professional welder who is going to charge me 80Euros for 5 or 6 tack welds on the bottom inside panel of the door. So, as I have some more repairs to do I'm going to have to learn how to weld properly. (on scrap metal first, of course). Various websites I've looked at are a bit confusing so maybe someone on this forum can point me in the right direction as far as consumables are concerned,. So my questions are if I'm welding 0,8mm metal...... Is 0,6mm flux core wire okay to use? Is gas better and if so do I use a solid wire? There is a grey wire, which I have now, but I've seen a copper coloured wire for sale too. What is the difference? I think the correct gas would be Argon/Co2 mix? Also should the regulator on top of the gas bottle have a gauge on it or is the gas released when I pull the trigger. Thanks in advance for your help and advice. I'll probably have a few more questions further down the line, but I don't want to buy the wrong stuff.
