I have a HH 175, I can move the contact tip back and forth about an 1/8 of an inch, is this normal? I pulled the nozzle off as well as the welding tip, down to the liner and it moves as well - is this normal, as well? Also, should the nozzle be seated all the way down on the gun or can I position it so that it is even with the contact tip. Thanks for your input.
