I noticed that on Miller's website there are 3 types of nozzles for the M-25 gun.
1 - the nozzle is flush with the tip, 2 - the nozzle extends past the tip and 3 - the tip extends past the nozzle.
Why are there different types, when would you use them and why? None of my welding books explains why!
Which should I buy?
Thanks ahead of time for your input!
