MACHINE DESCRIPTION
Thank you for purchasing a TRADEweld product. The TRADEweld Mig 250 M is a Multi-Process
welder that incorporates Mig, TIG and MMA welding in one unit.
Adopting the most advanced inverter technology, it uses power Inverters and PWM technology,
which works by rectifying the mains AC input voltage. The rectified input voltage is then inverted
and filtered to a smooth DC current. The smoothed DC current is then sent through power
switches (Mosphets) which convert it back to a high frequency AC voltage. The AC voltage is then
stepped down by a transformer and rectified to DC. The rectified DC is then filtered and smooth for
a usable power output for welding.
The development of inverter welding equipment has massive benefits which include greatly
reduced size and weight, greater power efficiency, multi-process capabilities and many more. The
inverter welder’s power source produces a much stronger and concentrated stable arc which
results in better quality and more efficient welds.
In MMA mode, this unit is a constant currant DC MMA (Arc) inverter welder.
In Mig mode, this unit is a constant voltage DC Mig (Gas) inverter welder.
In TIG mode, this unit is a constant current DC High frequency start TIG inverter welder.
The Multi- process Series are very efficient and robust. Using advanced technology coupled with
an array of adjustment controls they produce superior welds. The compact size and weight with it
being on wheels and a place to secure the gas bottle to the machine makes it a perfect candidate
for moving the machine around the workshop with the bottle attached.
A facility has been made for the fitment of a Spool Gun (Not supplied) to be connected for ease of
aluminium welding.
