Hi Ray,
While I'm probably a bit late in responding to the welders issue, I just
experienced what you are talking about. I talked with a technical guy who works
directly for Lincoln and he was very helpful. I also have a friend of many years
who makes his living welding pressure vessels and he is coaching me. Both these
people confirmed that a Power MIG 350MP is the appropriate welder for the work I
am doing with 1/2 inch Grade 70 steel. It has a computer to control arc length
and temperature which is not necessary but sure is nice. Unfortunately the
package cost is around $3,500.00. If your steel is lighter you can get by with a
smaller unit.
For Grade 70 ALL professionals that I spoke with said use flux core wire
and Carbon dioxide gas to improve penetration.
Best Regards,
Jim Kocourek
