4TT 400 Amp Tweco Tite® Style Electrode Holder

EDIT: The first one I ordered was defective. The rocker inside the head was stuck and I also couldn't twist the handle because the thread inside the head was badly machined. I asked for another one. It arrived today. The thread inside the head was OK this time but the rocker keeps getting stuck just like in the first one! So basically this is an overpriced piece of garbage from Tweco... I should've bought a Stinger V.

If you want a twist grip stinger Tweco is the only brand worth buying. Trust me!
