Fast Payback

■ 2 Welds achieves payback

■ The use of a trailing shield of some kind for titanium welding is almost mandatory, for the applications where the product cannot be placed inside a Welding Enclosure

■ When welding smaller titanium components, that could be placed in a Welding Chamber of some kind, Trailing Shields might be dramatically more cost effective than the use of a Welding Chamber
