Issues out of the box

June 18, 2019

Bought this gun as a spare for our weld shop and finally put it to use yesterday 6-17-19. Right out of the box there were issues with random porosity. I ran through everything from one end to the other and saw nothing out of place. the problem continued and we swapped it out with the gun off of a back up machine and no more problems.

Cyberweld has a great selection and ships quick along with killer prices. Miller changing a perfectly good gun for this one that shares not one of the same consumables.
