I am a farmer have gas weld before and I have a Lincoln four cylinder gas welder. It sticks my equipment together been at that over years 40 years or more. I thought I would do some TIG welding did research came up with a CK worldwide 200 watched a lot of videos, it came with old-school long collet and cups I put on about 10 hours did not do well tungsten stuck, sharpening, tungsten, steady, called ready weld. I got Kevin I told him my story I see your advertised the CK worldwide glass stubby lens. Kevin said I’ll fix you up he also tags very informative It arrived in about six days I put it on. I did not have to sharpen my tungsten for over an hour, so from an 10 hour TIG welder point of view, I went from
Sharpening sharpening tungsten’s every 10 minutes to once in an hour or more for me the benefit of the glass lens the colic short stubby was amazing I am 70 years old. The 200 series, world wide, TIG welder. Works well for me. I am now welding the seats for my home build aircraft that I fly now.
