Most auction companies ask that you pay when you are finished bidding. Some may ask for downpayments when you register, as in auction of real estate. In many equipment auctions bid-assistants will ask for deposits as your purchases are increasing. It’s good to ask about this prior to attending so you are prepared when you arrive. For absentee bidding you may need to give a credit car and expiration date for payment, if you are successful.
