On page 28 of the 375 Manual it shows a break-down of the torch tip end. It shows two sets of images one shows a Retaining Cup ( 202 808 ) and Tip ( 176656 ), it then shows a Drag Shield ( 225616 ) Retain Cup Drag Shield ( 225672 ) and Tip Drag Shield (225671 ). Numbers in brackets are Miller Part #.
I just got my 375 about 2 weeks ago and it did not include the drag tip.
When I look at the manual I can see that the Drag Shield mounts on to the front of the Drag Shield Retaining Cup - the Retaining cup is the large round cover that you remove to replace the tip and electrode. If the cup on your Torch is a 2 piece unit, cup/shield then I would say it is the Drag setup. If it is just a round fiber tubed with a brass threaded insert and tapered to a flat spot where the tip protrudes it is not a drag cup.
What is does not say is which configuration is STANDARD.
In the ICE 27C/T Consumables Kit sold by Miller that 202-808 Non-Drag Retaining Cup is included as well as the 176656 Tips and 175655 Electrodes.
Now according to miller web site the 375 cutting capacity is as follows.
Rated 5/16 Quality 3/8 Sever 1/2
Using a 1/16" Standoff it goes like this ...
Rated 3/8 Quality 1/2 Sever 5/8
I have included two photos .... cup1.jog shows the cup that comes with the 375 and also in the consumables kit. If yours looks like this, according to the manual it is not the Drag version.
cup2.jpg shows the part number on the tip of the cup as well as close of of the lip. If I had a Drag Ret Cup I would show that but I do not.
Hmmm a search brought up this link to a dard PDF file but it mentions the drag parts ( this is for the Extreme version but the Torch is the same and is shown on page 3 of the PDF )
