Ive had the titanium 125 for over 3 years. Its quite a nice welder. I have the helmet set to lowest setting because the t125 arc isnt very bright. Sometimes i point a spot light or flashlight at the workpiece for better visibilty. When doing a long weld with flux core, you want to drag your gun with the tip torward the new weld. When watching mig welders with gas, You will probably notice welders with push the gun torward the unwelded seam. Its just one of many differences between the flux and mig with gas processes.
