The 3035 gun is advertised for new models in this class. I would contact Hobart To see if you could get an adapter or wire one up.

Northwelder is right, the 3035 is the correct spoolgun for your HH187. You will also need the SGA-100 spool gun adaptor to connect the 3035 to the HH187.

The Spoolrunner 100 is designed for direct plug-in to the HH190 and HH210MVP only.

One of the internet welding suppliers used to advertise a way to make a DP-3545 fit other welders besides the ones it was designed for. They may have something for your situation. Check Ebay. I have no idea if their adapter set-up actually worked, I just remember guys talking about it here.

I had posted about this before - I too had a H187 and wanted a spoolgun. I looked like by the time I bought the SGA100 and the 3035 spoolgun, I would of had about $700 (shipping/taxes/etc) into the deal.
I ended up buying the Miller M211 (The Hobart H190 or H210MVP weren't out yet) with spoolgun. They had a combo deal with rebate at the time for about $950 total at my local LWS.
The prices have come down some since then too for the 3035 spoolgun - the SGA100 is still about $300.

I must admit, I liked the bead and weld of the H187 better than the M211.

Not only are the connections different, the HH187 doesn't have external power for the spool gun feed motor.

If you're willing to modify your welder, you can make it work.

What you'll have to do is install an AMP 97-3102A-18-4S socket plug in the welder (or a 97-3107A-18-4S if you want to just have it hanging on the outside of the welder). On two pins you solder the trigger wires that are on the front of the HH187. On the other two pins you solder the power wires from the motor. You'll also have to intall an SPDT switch so you can switch the power to the internal motor or the spool gun connector.

I don't recall off the top of my head which pins in the connector do what, but with a multimeter you'll figure that out quickly enough.

The Spoolrunner 100 simplifies this a lot, since it's internal motor is 24V, like the motor in the HH187. Previous spool guns are pretty much all 36V, including the 3035.

Of course, this will void the warranty on your HH187, so I wouldn't recommend doing this mod if you still have warranty left.

Edit: A thought just occurred to me. The SR100 might not use the same plug as the 3035, in which case the Amphenol part numbers I mentioned won't work. You'll have to double check this first.
