GAS CYLInDER AnD REGULATOR COnnECTIOn
WARNING: Cylinders are highly pressurized. Handle with care. Serious accidents
can result from improper handling or misuse of compresses gas cylinders. Do not
drop the cylinder, knock it over, expose it to excessive heat, flames or sparks. Do not
strike it against other cylinders.
The bottle (not supplied) should be located at the
rear of the welder, securely held in position by the
chain provided.
For safety, and economy, ensure that the regulator is fully
closed, (turned counter-clockwise) when not welding
and when fitting or removing the gas cylinder.
•
Turn the regulator adjustment knob counter-
clock wise to ensure the valve is fully closed.
•
Screw the gas regulator fully down on the gas
bottle valve, and fully tighten.
•
Connect the gas hose to the regulator secu-
ring with clip/nut provided.
•
Open the cylinder valve, then set the gas flow
to approx. 8l/min. on the regulator.
•
Operate the torch trigger to ensure that the
gas is flowing through the torch.

Your Mig welder is designed to accept either 5kg or 15kg wire spools.
Wire spools aren't supplied with the unit and must be purchased separately.
Ensure the gas and electrical supplies are disconnected. Before proceeding, remove
the nozzle and the contact tip from the torch.
•
Open the side panel. Loosen the nut of the spool holder.
•
Remove the plastic protection from the spool. Place it on the
spool holder and fix it tightening the nut.
Tighten nut to appropriate tightness. Excessive pres-
sure strains the wire feeding motor. Too little pressure
does not allow the immediate stop of the wire spool at
the end of the welding. Loosen and lower the plastic
knob (A) (fig.5). Open the pressure arm (B) of the
feeder. Extract the wire from the torch liner (E).
•
When the wire is disconnected, grasp it with pliers so that it
cannot exit from the spool. If necessary, straighten it before in-
serting it in the wire input guide (C). Insert the wire on the lower
roll (D) and in the torch liner (E).
WARNING: keep the torch straight. When feeding a
new wire through the liner, make sure the wire is cut
cleanly (no burrs or angles) and that at least 2 cm from
the end is straight (no curves). failure to follow these
instructions could cause damage to the liner.
•
Lower the pressure arm (B) and place the knob (A). Tighten
slightly. If tightened too much, the wire gets locked and could cause motor damage. If not tighten
enough, the rolls will not feed the wire.
WARNING: When changing the wire diameter being used, or replacing the wire feed
roll, be sure that the correct groove for the wire diameter selected is inside, closest
to the machine. The wire is driven by the inside groove. feed rolls are marked on the
side identifying the groove nearest that side.
the power supply cable to the power output line. Turn on the switch. Press the torch switch. The wire
fed by the wire feeding motor at variable speed must slide through the liner. When it exits from the
torch neck, release the torch switch. Turn off the machine. Mount the contact tip and the nozzle.
