I retired in 2020 after 41 years as a certified welder for Norfolk Southern Railway (yea, the Ohio fireball people!), but did tons of sideline work over those years as well. General fabrication & repair, and after buying the MP4000, a massive amount of ornamental iron railings and things like that. This machine was always at the ready, and never once let me down! Thanks for manufacturing such a durable and useful product, and thanks for your quick response!
