Suggestions on how to troubleshoot mig welder

Hey guys I have a Hobart 140 mig welder that has served me well . Last time I tried to use it 2 months ago the drive wheel/motor that pushes the wire was not working . When I pull the trigger there is a solenoid click but no movement of the drive wheel .

Anyone ever have a similar problem ? The nozzle appears to be clear and I don't think the issue is in the hose or trigger hand assembly . Anyone know what voltage the drive motor runs at ? I want to pull the connector that feeds the motor to make sure it is getting power when the trigger is pulled .

Worst case I will call Hobart and see what they say . The welder is in near perfect condition so well worth repairing . Any advice appreciated .
