Got a new addition to the shop, this Meco came from TM Technologies, or TinManTech. I got it hooked up last night and ran a couple passes.
Let me start by saying I am not a gas welder. I have a Henrob torch that I have found awkward to use, likely the operator, so I have always used either MIG or TIG. This video shows my second attempt with the Meco, the first attempt I did not have sufficient heat as I was worried about blowing holes. The two “scraps” were picked off the floor and tacked together about every 3/4”, then fusion welded the distance shown, yielding a full penetration weld with nice HAZ conisistency. Very impressed with the light weight and ease of use, even for an old dog learning new tricks. Video shows in order: front, back, planished, and bent at 90* for our destruction test.

Very impressed with this torch, one handed valve adjustments are a breeze, light weight and easy to use..
