The maintenance contract is probably very relevant in day-to-day business operations but easy to overlook otherwise. I'm not intimately familiar with this type of work but get the impression most (structural) welders are responsible for their own equipment (and operate their own company/business) or Big Construction Co. rents whatever welder they need from Enterprise Rental Co.
