Long story short
- be sure you are runing it DCEN if it is gassless wire (electrode on negative)
- Use a long stickout (3/4 to 1 inch between end of contact tip and metal) this preheats the core
- You do not need the nozzle with gassless flux.
- use side to side (weaving) motion do NOT back up and weld over the slag
- voltage = weld width
- wire speed = penetration + filler
this is true on all wire welders
Very interesting. Welder buddy was telling me to get closer to my work, <1/2", but I kept creeping out because I can see my bead better with the handset a little further out. He also had me laying the bead in small lazy circles, cutting with the forward stroke and feeding the puddle with the back stroke.
