We have used Ridgid 535 and 1224 pipe threaders for years without any problems. Recently our employer purchased two 535A's for cutting and threading rigid galvanized conduit. The automatic jaws on these new machines look like they could twist a piece of conduit into a pretzel but we are lucky if they even grip the pipe hard enough to thread it. We have had instances when threading 2" conduit at the owners manual recommended speed the jaws just slip on the pipe when engaging the properly adjusted die head. When reaming a piece of conduit the reamer actually pushes the pipe into the jaws before they grip the pipe. When we are done threading the pipe all that is necessary to remove it is to wiggle it a little bit. Has anybody else had this problem and is there a fix?
No announcement yet.
