I have a Miller 250dx , and it came with a diamond back torch kit. Ive heard people talk about using a gas lense. what exactly is a gas lense??? Is it the same thing as a cup?

 

a gas lense is a screen inside your gas cup that diffuses the shielding gas and makes a broader blanket. theyre worth the cost. easier to keep from contaminating your filler.

 

the local guy says some swear by it and some dont. Have you used one?? and if so... You think its worth it right??

 

 

They're worth it. Get the biggest one you can find... and only use smaller ones when you can't get in tight corners or something. Gas lens cups are different from the regular cups, so you will need to get bigger cups to fit the gas lens.

 

^^ listen to whatever this guy tells you.
