We do not provide remote electrical approvals, welding procedure qualification or diagnosis of a failed structural weld. Those questions need a qualified local professional.
Product and safety questions
For a machine problem, contact the manufacturer or the seller that supplied the unit. Keep the serial number, order record and manual. For a panel, outlet, breaker or gas installation question, use a licensed electrician or gas supplier.
For urgent exposure symptoms or a fire risk, leave the area and contact the appropriate emergency or medical service.
