WeldForce™
Productivity, performance and durability
Kemppi WeldForce™ MIG/MAG machine range provides productivity, performance and durability in welding.
WeldForce™ is the reliable choice for rough field conditions; incorporating heavy-duty wire feeder and the latest
welding power technology and digital control. Choose WeldForce™ on arc performance alone and you will ensure
adaptability and variety of process control at the point of application. WeldForce™ is modular by design, allowing
customers to choose the specification that best meets their needs. Three power source sizes (350A, 450A, and 550A) and
four different feeder options guarantee customer choice by selecting the combination that best suits the application.
The new WeldForce™ wire feeders represent new levels of durability in wire feeder design and construction; using
impact resistant strong, plastic casing Kemppi ensure significant reductions of wear and tear in case-materials. If you
need powerful basic MIG/MAG machines with accurate parameter control or more advanced synergic MIG/MAG,
WeldForce™ is the ideal welding solution.
WeldForce™ range
• Gas-cooled: 350, 450 and 550 A
• Liquid-cooled: 350, 450 and 550 A (with a separate cooling unit)
All of the Gas- and Liquid-cooled models are also available as multi-voltage machines (230 / 400V 3ph).

WeldForce™ – maximum arc performance
Kemppi always pays special attention to arc
performance and WeldForce™ is no exception.
WeldForce™ offers choices in filler material and gas
programs selection, providing fine arc control and
adjustment in a variety of applications and materials.
WeldForce™ includes specific control selections of
ignition and weld termination. Hot start, creep start
and crater filling controls meet the demands of busy
users and the changing workshop needs throughout
the working day. WeldForce™ Synergic includes 46
Synergic programs and parameter memory selection
guarantees the recording of optimum weld settings.
