Bought my unit in December 2012, and I needed to learn the new gun shape design, because I have welded for over 30 years. Multiplaz is easy to take apart, just read the instructions! Do not overthink the tool! Here are a few of my projects so far:

Bucket on steer skid loader- cut out rust and rewelded the plate. Steel.

Repaired the barbeque, repair needed refabricated part.

Welded on 4 wheeler broken pieces on bracing of fenders, welding on axle bearing.

The unit has paid for itself so I was able to get rid of my acetylene.
