i never used that model but i switched out my weldcraft for parweld because of quality issues with the weldcraft torch and its really good and the caps and cups are all the same as the weldcraft parts. I used a thumb control a couple years ago and didnt like it, i found it was just making more for your hands to do when i had two feet doing nothing. I found the foot control much better for myself , just my 2cents
