I have a really old huge Miller Dialarc which embarrassingly I can't actually use and have to get a mate in to do any bits I need doing!
Recently it's been leaving really untidy welds with black scorch marks around, does anyone know why this is? He's a good lifelong experienced welder so it won't be down to his technique or how he's set it up, there must be something wrong with the machine.
I can go deeper in and get the model number, pics of what the weld looks like if it's important.
TIA
