I suppose one method to prevent cold starts is the use of run on, run off plates, can't say I used this method using mig on lcs, but have when mig welding thick al/al. Could be tested with destructive test on say a t-fillet lcs, one with, one without run on/off plates to see the difference, if any?
Ps, real life welding position can make the use of plates not practical I suppose too?
