“Problem solving. I would say that is the biggest asset Zach has brought to our company since he first stopped in 2 years ago. We turn around TIG welded stainless steel on a regular basis. Zach introduced us to the TIG Brush system, which has saved us time and money. We’ve also been able to sell new customers on this new value-added process we provide. I appreciate Zach’s thoughtful insight, each and every time we are stuck without a solution. Weldstar has really become a valuable partner to our company growth. Thank you to everyone at Weldstar. ”
