My old boss blew out three power cables within a week on a brand new Syncrowave. For two different reasons, but it still boils down to the same thing. You either need to have a fuse block, a coolant flowmeter in the welder, or wire the cooler to come on with the welder. Forgetting to turn the gas on is embarrassing, but pretty painless, forgetting the cooler is a meltdown. Yes, you can get replacement power cables. They usually go first but there is also a slim chance of torch damage from lack of coolant, so check it out good when you have it apart. Check for proper coolant flow and any leaks.
Long arc, short arc, heliarc and in-the-dark!
