Question about Welding Tools
We have a Miller S-54 D 115V digital wire feeder ran off a Deltaweld 451 / Constant Voltage dc Welding Power Source that when you start to weld the wire speed controller drops to 0 but the wire feeds at almost full speed. The weld is just a big glob and does not penatrate the metal. I have checked all the grounding connections all the cable connections to the power source and all the wires inside the wire feeder. What might be causing this problem? thank you

Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

Weld Cable (+) To Feeder lead cable.
Work Cable ( - ) To Workpiece Weld cable and work cable connections to power source (DCEN/DCEP) are dependant on wire type.
Since feeder is not polarity sensitive, there is no need for an electrode polarity switch.
Voltage Sensing Clamp Connect voltage sensing clamp to
Gas Hose to regulator.
Gas Cylinder to regulator.
Use of shielding gas is dependant on wire type.
You are all set up to weld.
