Ordered .030 and received item marked .030 Will not fit through Hobart .030 contact tips. Seems closer to 0.035 than 0.030. No 0.035 tips available to test. So much to save! Update: The .030 contact tips I had on hand were Hobart #770176. Apparently Hobart made another .030 bar #770177 that this wire will run through. Use this advice; I would give the item 4 stars.
