My Gantry Crane Build

Changes to the gun are not required. I wanted a longer MIG lead so I replaced my original gun with a 20' one. The nozzle of my original gun was also electrified when welding so the edges would burn away or stick when contacting my work, such as in tight inside corners.
The gun and nozzle/tip that came with your 275p can be used to spray. They just aren't the ideal setup so your gun may heat up quickly when welding heavy material.
The reason I changed my front end parts of the gun was to reduce heat conducted into the gun. My nozzle is insulted from the threads and I use a tapered contact tip that runs much cooler in spray.

Hmmmmm....interesting. In listening to that I might follow suit, but more to have two available configurations. I'd use the config that came with the welder for short circuit MIG and the new one for spray.

I will likely inquire further when the time comes.

Thanks again!

I use the same configuration for everything now other than aluminum. This machine and gun are tougher than Tarzan's toenails.

Yeah well I'll give ya that having two separate MIG configurations could become a hassle to change between. So there is that. We'll see how it goes. I have another project in the works, so this may happen sooner rather than later...
