FABRICATOR 210
Manual No. 0-4855 4-3 OPERATION
Positive and Negative Welding Current Terminals
Refer back to Figure 4-1. Both terminals located at
the bottom of the unit are shown without the terminal
knob. Both knobs must be firmly secured before
attempting to weld.
Gun Polarity Lead
This lead selects the welding voltage polarity of the
electrode wire. Attach it to the positive welding terminal
(+) when using steel, stainless steel or aluminium
electrode wire. Attach the Gun Polarity Lead to the
negative welding terminal ( - ) when using gasless
flux cored electrode wire. If in doubt, consult the
manufacturer of the electrode wire for the correct
polarity. Also refer to section 3-16.
Positive and Negative Welding Terminal Knobs
Welding current flows from the Power Supply via
heavy duty terminals. It is essential, that these terminal
knobs are tight to achieve the necessary electrical
connection.
CAUTION
Loose welding terminal connections can cause
overheating and result in failure of the
terminals.
Gun Switch Receptacle
The Torch Trigger 4-pin receptacle is used to connect
the two wires from the torch gun to the Fabricator
210. Only pins 1 and 2 are used for this.
To make connections, align keyway, insert plug, and rotate
threaded collar fully clockwise.
