AFTEK is the sole remaining manufacturer of resistor controlled welding machines in the USA. In 1977,
Big 4 Manufacturing introduced their innovative
Series 77 Control, and the features introduced then remain at the heart of the AFTEK design:
Edge-wound coils for better heat dissipation (thus better current control) and rotary switches for current selection.
One of the oldest welding technologies combined with one of the newest electronic switches makes an unbeatable combination for the TOUGHEST welding jobs.
