FitWeld Evo 300 [8/20] Installing filler wire

FitWeld Evo 300

2.4.4 Welding gun

Connect the welding gun cable to the Euro adapter socket located on the front panel and

hand tighten only. Do not over tighten the collar.

The welding gun leads the ller wire, shielding gas and electric current to the weld piece.

When you press the welding gun trigger, shielding gas will ow and ller wire will begin to

feed.

The arc will ignite when the ller wire touches the weld piece. If no ignition, check that the

earth return cable is connected and the clamp has good contact to the work piece.

2.5 Installing ller wire

With FitWeld Evo 300 you can use up to 200 mm diameter wire spools and the following ller

wire types:

• solid wires

• ux-cored wires

• self-shielded ux-cored wires

• stainless steel wires

• aluminium wires.

When choosing the ller wire, remember that the wire must have approximately the same

melting point as the base material to be welded.

NOTE! When changing the ller wire, always check that the feed rolls, their groove shape and size

and the wire liner inside the welding cable are suitable for the wire you are using. Also check that

you are using right polarity for the ller wire.

2.5.1 Mounting the wire spool

NOTE! The liner and the feed rolls are colour-coded. See that you are using feed rolls that match the

colour of the wire liner inside the welding gun cable. See the table of feed rolls and wire liners later

in this chapter.

With FitWeld Evo 300 you can use wire spools with a diameter of 200 mm maximum.
