We do a lot of work for several Alirine support companies..... this job was the addition of a drawbar reciever monuted to the front of a Jet Blue tug. The company supplied the reciever and I burned a pices of 3/4" x 4" plate to mount the reciever on which in turn gets mounted to the tug.Process used..... and parameters;For the flat welding which is the the position I used to weld the reciver to the mount plate.... Process, MIGWire, Hobart Excel Arc 71 Dualshield, 1/16"OVC (volts), 32Feed, 250 IPMGas, 75/25 35@ CFHFor the vertical up, and overhead.... Same as above except for,OVC, 27Feed, 175 IPMRemovedthe paint from the front of the Tug and locate where the hitch will be mounted.One pass, vertical up, no stop and restart.One pass, vert up, 1 stop and start (I had to reposition)Overhead,one pass. The weld closest to the bottom of the pic is the overheadMounted.... then painted....Thanks for looking...._________________Chris

Reply:Wow, that should hold it!Nice job.Curious if you think the colder vertical/overhead parameters would also work ok in the flat, seems like it.

Reply:Humm - looks like a Tug M1 from what I can see of the front bumper.  That model was designed back in '93 while I worked there.  There are probably a few parts on that tractor I designed - but it's been so long I don't remember off the top of my head.  That was about 2 lifes ago!Tug was a cool place to work - lots of welding opportunities.  There was one guy named Gabe that did all the hitches - he was amazing at weaving a 1" wide vertical up!  He had 2 machines it his welding bay; one running .041 regular MIG and one running .051 "innershield" that he did most of the hitches with.  All of the mig welding machines when I was there were miller 400 and 600 amp power supplies with S52 wire feeders and monstrous big tweeco guns.  Even the prototype shop had that set-up and it took me a while to get used to that big gun after leaving the shop that used miller 200's to build trailers and roll cages.Sorry - seeing that Tug brought back memories...Jason
