For 5 years I was a welding engineer for ITW welding group (the parent group of Miller, hobart, weldcraft, tregaskiss, Bernard, and numerous other welding companies). I was primarily focused on filler metals on the hobart side but worked with Miller heavily and the others as well, supporting the entire process from filler metals to power sources. I left to work in automotive (the pay is WAY better) but do miss working on the supplier side sometimes.
