• Control lead for wire feed unit
• Insert the end of the intermediate tube package through the strain relief and secure the lock by turning
to the right.
• Insert the plug on the welding current lead into the "+" welding current connection socket and lock.
• Lock the connecting nipples on the cooling water tubes into place in the appropriate rapid-action
closure couplings:
Connect the red return line to red rapid-action closure coupling (coolant return) and
the blue supply line to the blue rapid-action closure coupling (coolant supply).
• Insert the plug of the control cable into the 7-pole connection socket (digital) and secure with the
crown nut (the plug only permits one position).
• Connect the crown nut on the shielding gas lead to the G¼" connecting nipple, connect the shielding
gas.
A pilot static tube is factory-fitted onto the wire feed unit for a gas flow rate of 0-16 l/min. For
applications where a higher flow rate is required, a pilot static tube of 0-25l/min (see accessories)
should be fitted.
