My elderley SIP 130 will soon be up for grabs; its one of the old style SIP's with better wire feed; its been used and tested to its limits over the years...outstanding welder for what it is- always gets the job done.... Theres an upgrade apparently on these older SIP machines to make them 150 -, but at the mo at 130 output it welds up to 3mm plate no bother -swan neck needs replacing -good otherwise; €120...
