Binzel 24 style mini spool gun with Euro fitting. The mini spool gun is great for aluminum MIG welding as it helps eliminate feeding problems associated with soft aluminum wire. The spool gun improves the "feedability" of aluminum wire by locating a small 0.5kg, 100mm diameter spool of wire on a pistol-grip style gun. Because spool guns only need to feed the wire just a few millimetres before it hits the weld puddle, they eliminate the potential problems created by pushing soft aluminum wire 3 or 4 metres through a regular gun. By using a spool gun, you'll spend more time making better welds and less time cursing at a "birds nest" of wire tangled around your drive rollers.
