  1. welder_morrison

    The quality is good. We use the machine everyday in our shop and so far no issue. IÔÇÖm happy with this machine and would buy more welders from them.

  2. Tony

    Easy to switch between different processes. Good size welder

  3. Niaomi

    Impressive machine. With all features that the machine has and being made in Canada it has a very reasonable price. Good job Canaweld.
