ASSEMBLING THE UNIT cont'd
Electrical shock can result when contacting live
electrode or internal components
Electrical shock can result from absence of
grounding lug.
Welding machine must be connected to
power source in accordance with applicable
electrical codes.
Do not touch electrode or internal compo-
nents without protection.
Disconnect power before servicing.
Do not remove the grounding lug in any elec-
trical plug.
Electrical shock can cause injury.
Install the current nozzle and gas nozzle.
Open the tank valve and adjust the gas fl ow to 20-30 CFH
using the fl ow meter regulator.
During welding, the display screen
A
displays the
actual work current and voltage. The displayed values
may be slightly different to those set. This can depend
on numerous different factors-type of torch, thickness
different to nominal thickness, distance between current
nozzle the material being welded, and the welding speed.
At the end of the weld, the current and voltage values
remains in memory in the display
A
; to view the set
values, slightly turn the knob
B
.
If you press the knob
B
without welding, the display
A
shows the open circuit voltage.
SET-UP FOR WELDING ALUMINUM
•Remove the wire guide
tube located inside the
torch adapter
C
.
• Replace the wire feed roller (see fi g. 3), with the roller
suitable for the aluminum wire you have to weld.
• Install the torch prepared for aluminum.
PREPARING THE STEEL TORCH FOR WELDING
ALUMINUM USING OPTIONAL ALUMINUM KIT (MIG
160AK) AND OPTIONAL ROLLER (CKS 3080942).
•Remove the metal liner
located inside the wel-
ding torch, see fi gure.
•Insert the carbon tefl on
liner, see fi gure.
•On the liner protruding
from the torch, insert the
brass mandrel, the O-
ring and the locking nut.
The nut should be hand
tightened. If it is too
tight it may impede the
feeding of the welding wire.
•Cut the carbon tefl
• Do not use the brass tube included in the torch prepa-
ration kit.
MIG WELDING WITHOUT GAS
Install a reel of fl ux cored wire for welding without gas
and select the adequate synergic curve (
E71TGS 0.35"
),
following the instructions described in the “service
functions (
PROCESS PARAMS
) paragraph.
Extended welding with fl ux cored wire will cause the end
of the torch to get hot. This could melt the cover and end
of the torch. Please order part number MIG1608 (heavy
duty torch) if you plan to do a lot of fl ux cored welding.
Fit the wire roller suitable to the 0.035" diameter fl ux cored
wire and the current nozzle on the welding torch.
Connect the terminal of the ground lead, inside the
reel compartment, to the positive pole, while the lead
coming out of the dividing wall must be connected to
the negative pole.
Connect the ground lead clamp to the piece to be
welded.
