the roller back on so the race corresponds to the wire
used, see fi gures 3 and 4.
• Cut the wire with a well-sharpened tool, keeping it
between your fi ngers so that it cannot unwind, insert it
inside the plastic pipe exiting from the gear motor and,
with the aid of a fi nger, also insert it inside the brass
adapter, see fi gures 5-6-7-8.
• Close the drive arm, being careful of the wire, which
must be aligned with the roller race, see fi g. 9.
• Fit the welding torch.
After fi tting the reel and torch, switch on the machine, select
the suitable synergic curve, following the instructions given
in the service functions (PROCESS PARAMS) paragraph.
Remove the gas nozzle and unscrew the contact tip of
the torch. Press the torch button until the wire comes out
.
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 contact tip and gas nozzle.
Open the tank valve and adjust the gas fl ow to 20-30 CFH
using the fl ow meter regulator.

SET-UP FOR STEEL WELDING
• Replace the wire feed roller (see fi g. 3), with the roller
suitable for the steel wire you have to weld.
• Install the torch prepared for steel.
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.
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.
DIFFERENT TYPES of WIRE
• Flux cored wire
This is typically used for outdoor repairs on steel struc-
A
tures, for thicknesses of .039" to .240".
• Steel (Fe), with either ArCO2 or CO2
The different curves allows to weld on steel structures
with a thickness of .024" to .236".
Consequently these curves are widely used in the car
body repair, as well as for other small repairs of steel
structures.
