I have not been actively working on Snowzer or a Snowzerblower for it due to other projects (honey-do things). The new Eastwood welder seems to work nice for my needs. One of it's features is a tack weld option where, when selected, only powers the stinger for 1/2 second. This feature is good for those instances where thin sheet metal panels are to be welded. More expensive welders have this capability where the timer can be adjusted to suit the need, usually up to 10 seconds. This would be useful for making stitch welds.
