SIGMA 400 STB
Synergy
M79541446
• powerful welding inverter for MIG/MAG
spray arc welding or short arc welding with
solid or flux-cored fire
• can also be used for electrode welding of
unalloyed or stainless steel
• Sigmas is ergonomic and user-friendly:
- rounded corners made of reinforced
plastic damp hits and protect welder and
prevent damages in welding cables
- embossing in side walls makes box body
strong and sturdy
- hoses and cables can be placed to the
handle in front of the machine
- protective cover on the control panel
protects from dirt and knocks
- high-wheeled trolley for comfortable use
• Duo Plus function: welder can better control
the weld pool and minimize the amount
of welding splashes as well as the need of
finishing for example in welding of steel and
aluminium
• sequential welding as standard: welder
parameters in the most common welding
operations can be strored in the data storage
- there is room for ten special settings,
which saves operating time
• user-friendly control panel: after the most
important parameters such as wire feed
rate and voltage has been setted the new
Sigma software together with inverter
technology makes professional welding
