Except for the internal water-cooling system, keep water and water containers away
from product. Water ingress can cause a short circuit, electric shock, or fire.
Keep free of dust and debris.
Do not install the product in any of the following environments:
damp environments where humidity is 90% or higher;
dusty environments; environments where chemicals are handled;
environments near a high-frequency noise source;
hot environments where temperatures are above 40° C / 104° F;
cold environments where temperatures are below 0° C / 32° F;
environments where water will condense.
It is not recommended that holes be drilled into the cabinet. Metal debris inside the
cabinet can cause a short circuit, electric shock, or fire. If holes must be drilled it is
imperative that all components are protected from debris. Drilling holes in the cabinet
may allow dust and other materials to enter the cabinet.
Individuals with cardiac devices should maintain a safe distance due to strong magnetic
fields arising from resistance welding. The function of cardiac pacemakers and
defibrillators may be disturbed, which may cause death or considerable health
damages! These persons should avoid the welding system unless authorized by a
licensed physician.
Always ensure cooling water is adequately flowing at the proper rate, temperature, and
is of sufficient quality. For water quality requirements, refer to AWS J1.2M/J1.2.2016
Guide Installation and Maintenance of Resistance Welding Machines.

2INTRODUCTION
2.1 Weld Control
The EN7000v2 Weld Timer Control is primarily a single-phase 50/60 Hz AC control. It can be configured for Single Gun,
Multi-Weld Cascade, Seam Weld, Roll Spot, Analog and 3 Phase DC.
Key Configurations of the EN7000v2 for AC & 3 Phase DC welding:
1) Available in two models, with or without Touch Screen on board programmer.
2) Phase Angle control and Constant Current can be combined in single or linked programs to reduce
expulsion on pre-heat currents.
3) Available Analog Control for certain Seam or Heating applications.
4) Available Multi Electrode configuration for cascade machines. This allows shorter cycle times in multi-
weld operations.
5) Available 3 Phase DC configuration (for use with Inside the Delta 3 phase DC Transformers). Allows
equal primary loading with improved power factor for higher current applications.
2.2 Features
The EN7000v2 weld timer control is suitable for various resistance welding and heating applications. These include spot,
spot repeat, projection, multi-welding, seam, roll spot including 0 to 10 volts Analog control. The EN7000v2 is available
with a range of SCR’s. From 300 Amp Air cooled SCRs to 5000 Amps Water-cooled heavy-duty SCRs. The EN7000v2
product range covers a high number of industrial resistance welding/heating applications that use pneumatic pedestal
machines, Cascade machines and including large coil joining seam welders.
The primary features are:
•Store up to 256 weld schedules (Programs)
•Data log for up to 6,000 welds
•Real time clock
•3 weld intervals: Pre-Heat + Main Heat + Post Heat
•Secondary or Primary constant current regulation
•Built in Ethernet/IP
•2 Analog Inputs
•1 Analog Output
•16 Discrete Inputs & Outputs (24 V dc short circuit protected, monitored guided contact safety
