Calling the kettle black.....
Nice job Stuart....... have you tried a copper backing plate to save on the grinding....?
Same process using the clamps but get a piece of copper from the scrap yard..... the heavier the better.... I have some 1/4 inch printing plates..... 3 by 7 from Cohen..... about $3.00 a pound..... brass blocks are also good and really absorb a lot of heat....
If you set up your copper plate behind the gap... held tight with clamps.... you could reduce you wire speed by 25% and your heat by 10%..... still get good penetration but much less grinding to be done on both side.
Have you tried the heat absorbing "gel" they sell for such butt welding..... said to be fantastic at soaking heat and reducing warpage......
Do you have to change your polarity on your Mig when you change over from .035 wire to .025....?
