the top surface of the middle shelf 117 and two cross bars namely middle cross bar 420 and top cross bar 410 affixed between the vertical support bars the partition 405 which effectively creates a left hand side and a right hand side of the middle shelf 117 serves to separate and or provide secure retention of welding equipment that is positioned in each of the left and right hand sides in addition as can be seen in fig5 the partition 405 is disposed on the middle shelf 117 at a position such that the left hand side of middle shelf 117 is larger than the right hand side of middle shelf 117 among other benefits this positioning enables the system to accommodate most standard sizes of welding equipment i e not only welding machines but also peripheral equipment such as power sources suitcase feeders and air coolers in that regard the specific equipment shown in fig5 includes a power source 505 and a suitcase welder 510 in a variation of the system 100 the partition 405 can be movable so that the relative sizes of the right and left hand sides of the middle shelf 117 can be varied other variations may involve i making the partition 405 completely removable to make the entire width of middle shelf 117 available to hold a single large piece of equipment ii using shorter partitions for example stubs that may be only an inch or more in.
