In general, the use of a grate rather than a clinker breaker does limit utility somewhat. You will have to poke slag through those salt-shaker holes or stop and clean the fire out more often. I say "somewhat" because I have used a simple grate-type, light weight forge with a hand cranked blower for portable demonstrations for the last 15 years with no serious problems, forge welding included. To see the other side of the coin, take this link:
Your first forge doens't have to be your last forge.
