Resistance Seam Welder works with controllers up to 6.0 kA.
August 31, 2011 -
Operating with capacitive discharge and high frequency DC controllers, Model RSX26 is suitable for joining conductive foil materials, such as copper, aluminum, and nickel - even if hermetic seal is required. Roller configurations incorporate copper hub and factory grade outer ring to join metals. Air-cooled, tabletop seam welder is controlled by WeldWorks Software Suite, which allows operator to set weld repetition rate and roller rpm on per part basis.

Resistance Seam Welder Upgraded to Higher Output
techMatrix, LLC of St. Paul, MN has upgraded their RSX26 Resistance Seam Welder to work with larger, more powerful weld controllers (up to 6.0 kA output). This makes the air cooled, table top seam welder suitable for joining highly conductive foil materials - like copper, aluminum and nickel - even if a hermetic seal is required. These materials require short, high energy pulses to be welded effectively. Both capacitive discharge and high frequency DC controllers with feedback control are suitable with the RSX26 seam welder.
techMatrix has also introduced new roller configurations that incorporate a copper hub and refractory grade outer ring to join conductive metals. The compact seam welder is controlled by the powerful WeldWorks Software Suite running on Windows 7. The software provides better control over the RSEW process by allowing operators to set the weld repetition rate and roller rpm on a per part basis. In addition to running the machine and storing weld schedules, the software collects all weld data from the controller. This gives the user full insight into their resistance seam weld process making it easier to obtain consistent quality.

seam welding
I have seam welding job as follow:
Material : mild steel
Thickness: 1.2+1.2 mm
Welding rate required: 4 m/min.
Seam welding machine has an inverter power supply type
What is the suitable machine power capacity and constant current for this job?
Best regards

Mohamed,
The power capacity depends, do you need over-lapping spot welds to make a hermetic seal or would a roll spot suffice? If roll-spot, what is the spacing, it comes down to duty cycle and the power for a single spot. Another factor is the width of the roller and the force. Without all this information, it is very hard to predict with certainty the power required.
