It`s hard to get a real grip on the capabilites of the Vantage. Sometimes you hear the Vantage doesn`t run and/or cap as well on pipe,including stacking iron,and then I hear from a friend of mine that ran a SA-200 for probably 20 years welding pipe who tried and liked the Vantage and said he noticed no difference in the two machines when pipe welding. He`s an ace welder working for an large union here in Michigan,he always has to test when going to any job and has no problem passing x-ray and bend tests,and his machine is always checked to make sure the amperage is within tolerance. I don`t know why others say it isn`t as good as a SA-200 on pipe. I believe my friend,I believe it`s all in the settings.As I said he is an ace welder and can weld circles around me.
