151 help

[mafiacustomz]

i was welding exhaust with my hf 151 the other day running mig with co2 gas. When i was welding the nozzle was getting welded to the steel sometimes but thats not the problem. The problem is the welder started making this hard dragging sound and stoped feeding wire fast. I am not sure but i think its the wire feed motor is burned up can it be anything other thin the motor is their a website to buy HF 151 parts.
