Moving the MIG around is easy if it has wheels but the gun harness, power lead and earth lead nearly always end up draped over the machine. They scratch the machine's paintwork and fall off with monotonous regularity, only to get run over and / or jam the wheels.
My solution is this - A simple Broom stale pushed inbetween the gas cylinder, its securing chain and the machine itself provides a nice perch, finished off with a generous bracket.
Now all of the leads hang up easily and there is no more draping, scratches or jammed wheels. Even the face mask has a home!
