3 & 4 Station Ironworkers

ProStar™ three-station ironworkers excel in capacity, quality of cuts, power, versatility and affordability. The PRS5614 machine is ideal for stainless steel or high-tensile steel.

Additionally, our four-station ironworkers allow you to move a pipe notcher from the notching station to the punch station, or from the punch station to the power cavity. You can load the three stations with different sized pipe notchers.
