6a. Flux Core (Gas-less) Wire Setup:

Remove the two Knobs securing the cables. Connect the Black Ground Cable to the rear, red, positive Terminal using the Knob.

Connect the Red Torch Cable to the front, black, negative Terminal using the other Knob.

This is the initial setup, called

Direct Current Electrode Negative (DCEN).

c. With assistance, set the cylinder (not included) onto a shelf or cart near the welder and secure the cylinder in place with two straps (not included).

d.Remove the protective cap from the cylinder (if present). Stand to the side of the valve opening, and open the valve briefly to blow dust and dirt from the valve opening. Close the cylinder valve.

e. Obtain an appropriate Regulator/Flowmeter

(not included) and close its valve completely.

 

 

Thread its inlet connector onto the

 

 

cylinder and wrench tighten.

 

 

Note: If the threads do not match, then the Regulator/

Flowmeter is likely for a different type of cylinder/gas.

f.Attach the Gas Hose securely to the outlet of the Regulator/Flowmeter using a hose clamp (sold separately).
