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