I've just assembled a new HH210. There is a wire feeding problem: it's too easy to stop the wire (either by fingers or during the wood plank test while adjusting the rollers pressure). When there is no resistance, wire feeding seems to be OK (as far as I can tell without performing any welding test).
The grooved roller is attached correctly. When the rollers are pressed together somewhere between #3 and #4 units of pressure and a small resistance to the wire is created, the motor behaves like it's overloaded and, finally, rollers stop rotating.
The spool is not tight, the solid wire is clean, there are no cross windings, replacement/removal of the contact tip doesn't help. I can pull the wire from the nozzle end (after opening the rollers) and feel no catching inside the liner. I, finally, attached my old HH187 gun, but it didn't solve the problem either.
Apparently, the problem is either in the motor or the feeding assembly.
When I press the trigger I can see sparks produced by the feeder motor (see part 43 in http://www.hobartwelders.com/om/part...78b_pt_hob.pdf). The sparks can be seen through the slot as pictured on the photo I attached. Is this sparking normal for the welder? Does your HH210 feeder motor produces spark when you press the trigger?
Thanks!
P.S. I'm going to call Hobart tomorrow, but until then I'd like to hear your opinions. I wouldn't like to open the unit since it's brand new and, if faulty, should be replaced, IMO.
