I recently received a spoolmate 100 spool gun. I am using it with the multimatic 200. I can lay down a good bead with the spray transfer on the flat side of the 3/4" x 3/4" square aluminum tubing 1/16" thick. However when I go to weld the joint sections, it looks like I am laying down worm droppings. Does anyone have some advice as what I may be doing wrong. 100% argon, 14 amps with 320 wire speed. This is what the setting is at for laying down the good bead on the flat.
Sounds like the weld is cold. Try turning the voltage up and adjust wire speed as needed. Also Check your ground. I find that when i ground one end of the two parts to be welded if my welding table is cleaned and shinned up the bead will start easier and cleaner. I wouldn't think 1/16" would need any preheat but ive been wrong before.
