Usage Notes

• Walking the cup is not recommended with glass.
• Keep the diffuser in its original shape; remove and reinstall it if it gets out of shape.
• As with all big-diffuser cups, start on low amps to stabilise the arc and make sure you won't arc off the diffuser. If it does arc, clean or regrind the tungsten. Low amps won't hurt the diffuser, but arcing at high amps can deteriorate it.
• Take care not to drop or knock the cups against hard objects.
