CONTROLS AND SETTINGS

 

 

 

This machine has the following controls:

 

 

FIGURE B.1

See Figure B.1

 

 

1. POWER SWITCH – Turns power on and off to the

 

2

machine.

 

 

 

 

2. ARC VOLTAGE CONTROL – This knob sets the

 

 

output voltage of the machine. Along with wire feed

 

 

speed (WFS) this control sets a weld procedure.

 

 

Refer to the procedure decal on the inside wire

 

 

drive compartment door to set a correct welding

3

 

procedure based on type of

material and thickness

 

 

being welded.

 

 

 

 

3. WIRE FEED SPEED CONTROL (WFS) – The knob

1

 

sets the speed that the machine feeds wire. Along

 

 

with arc voltage this control sets a weld procedure.

 

 

Refer to the procedure decal on the inside wire

 

 

drive compartment door to set a correct welding

 

 

procedure based on type of

material and thickness

 

 

being welded.

4. GUN TRIGGER – Depress the trigger to activates

 

 

the wire drive to feed wire and energizes the output

 

 

of the machine. Depress the trigger to weld and

 

 

release the trigger to stop welding.

 

 

 

5. WELDING GUN – Delivers wire and welding cur-

5c

 

rent to the weld.

 

 

 

 

a. Gun Liner – wire travels through the liner from

5b

 

the wire drive. The gun liner will feed .025” to

 

 

.035” (0.6mm to 0.9mm) wire. The 180A machine

5a

 

can weld with .045”(1.1mm) wire if an optional

5

.035"(0.9mm)

.045”(1.1mm) liner is installed in the gun.

 

NR-211-MP

b. Contact Tip – provides electrical contact to the

 

WIRE SPOOL

wire.

 

 

 

 

 

 

 

c. Nozzle – When flux-cored welding the black noz-

4

 

zle protects the mounting threads on the gun.

 

 

When MIG welding the brass nozzle funnels the

 

 

shielding gas to the weld.
