The 255 Lincoln wirefeed welder is designed to start by running the wire slowly at first. This allows you to establish the arc and a proper fusing, without piling up a bunch of weld material at the start of a cold weld. I really like the feature, but if I remember correctly, it can be turned off.
If you really want to get rid of the feature, you can go to the Lincoln web site and download the user manual. If you can't get the manual, PM me and I will see if I can find mine.
