Intuitive, Easy-to-UseProgramming Current, Voltage and Power Feedback Modes:

Constant Voltage:

•Compensates for parts misplacement and forceproblems•Reduces weld splash •ideal for round (non-flat) parts •Intuitive graphical user interface.•Dual pulse waveforms programmed in current,voltage,or power control modes.•Programming times to 100 Monitor current

Constant Power:

•Varies current and voltage for consistent energy •Breaks up surface oxides and plating •Ideal for automation to extend electrode life µ sec incrementsprovides ultimate control.•Accurate,built-in monitor displays the graphical“trace”of weld current,voltage,power and resistance,along with numerical peak and average values.•Easy-to-set limits establish process windowfor acceptable quality.•User programmable relays can be used inconjunction with visual and audible signals foroperators and automation interface. Monitor current or voltage

Constant Current:

•Delivers same current regardless of resistancechanges•Compensates for part thickness changes•Ideal for flat parts with consistent electrode topart fit-up Monitor voltage

Effective Weld Monitoring and Process Tools

Pre-Weld FunctionActive Part Conditioner (APC)Weld Stop

Run Screen – Shows that 2nd Pulse was inhibited from firing. Run Screen – Constant power first pulse breaks through oxides. Run Screen – Shows termination of weld current during weld pulse. Monitor Screen – Shows 1st Pulse weld current exceeded limit. Monitor Screen – First pulse time automatically compensatesfor varying levels of oxides. Monitor Screen – Shows weld current exceeding limit.

Sends an initial short,low energy pulse throughthe assembly,tests key electrical parametersagainst pre-set limits,and inhibits operation iflimits are exceeded. First pulse adapts weld time to displace oxidesthen terminates allowing a second pulse withupslope to complete the weld thus avoidingweld splash. Terminates the weld energy during the weldingprocess if pre-set weld current or voltagelimits are exceeded.
