If you can get by with it only put 3 tacks in ur coupon, less tie ins. Use ur grinder and try and make ur fit perfect as you can. If ur gap is bigger on one side of the pipe weld that side first so ur not stuck with A huge gap. Theres a few tips hope it helps.
A kinda way to cheat is put your long tack on the bottom so you dont have to spend as much time on bottom with the root pass kinda helps when you get going
