Just wanted some advice on how to tackle a project. The equipment I have available is a 200A inverter MIG: GMAW (100% CO2, ER70S-6 0.8mm) and FCAW (E71T-GS 0.8mm). I'm planning on building a car transporter over Easter (I've got a week off work). Obviously the first choice would be GMAW, problem solved. Unfortunately though I won't be working indoors. I've done a few small jobs outside with gas wire when I can't be bothered switching to flux core, but I find it difficult to keep welds consistent. They look OK but I am concerned about how strong they are. My options seem to be: 1. Try to use some sort of screen with GMAW to stop the shielding gas from being blown away. Problem is close to buildings that wind comes from all over the place, and it would be an awkward process messing about with screens. 2. Use FCAW and not worry about wind. Is it a good option for quite critical welds on a trailer though? I'm of the (possibly ignorant) mindset that GMAW is always "better". 3. Don't bother, GMAW outside is impractical and FCAW is not as strong. Edit: Had a thought, I use 8 LPM generally when I'm indoors. Would increasing it outside help?
