INSTALLATION – PRODUCT OPERATION
Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During
set up, the operator must ensure that the machine is unplugged. Connecting generators in a series or a parallel circuit is
forbidden.
HARDWARE DESCRIPTION
The MMAX7 are Inverter technology based welding machines, portable, single phase, fan cooled, for electrode welding
(MMA) in direct current output (DC). These machines can weld all types of electrodes: rutile, basic/low hydrogen, stainless
and cast iron. They’re protected to work with generators (230V +/- 15%).
POWER SUPPLY – STARTING UP
• This hardware is supplied wih a 16A plug, type CEE7/7 (Standard 13A UK plug in the United Kingdom). The machine
must be connected to a socket WITH earth 230V (50 – 60 Hz). The absorbed effective current (I1eff) is displayed on the
machine, for optimal use. Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with
the current needed by the machine. In some countries, it may be necessary to change the plug to allow the use at maximum
settings. Prefer a 32A for the MMAX7 in intensive use. The device must be positioned so that the socket is always
accessible.
• Starting the MMAX7 is done by positionning the switch on the desired current value (the sleep mode corresponds to the «
» value of the potentiometer).
CONNECTION ON A GENERATOR
The machine can work with generators as long as the auxiliary power matches these requirements :
- The voltage must be AC, always set as specified, and the peak voltage below 400V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements as several generators generate high voltage peaks that can damage these
machines.
MMA WELDING (ELECTRODE)
CONNECTIONS AND RECOMMENDATIONS
• Connect the cables, electrode holder and earth clamp in the connectors,
• Respect the welding polarity and required current indicated on the electrodes boxes,
• Remove the electrode from the electrode holder when the machine is not in use.
• Your machine has 3 features exclusive to Inverters:
- Hot Start delivers initial overcurrent to facilitate easy arc striking.
- Arc Force adjusts the arc voltage to compensate for the arc length increasing/decreasing
- Anti-Sticking technology prevents your electrode sticking to the work piece
TIG WELDING WITH INERT GAS (TIG MODE DC)
These machines can weld DC TIG with scratch start (MMAX7). Requires optional valve controlled TIG torch.
TROUBLESHOOTING
SYMPTOMS CAUSES REMEDIES
The 2 indicators are on, the machine
does not deliver any current. The thermal protection has switched
on. Wait for the end of the cooling cycle.
The green indicator is on, but the
machine does not weld. Fault with earth clamp/cable
connection. Check the connections
The product is under voltage, you are
feeling tingling when touching the
machine's body. The earth contact is faulty. Check the plug and the earth of your
installation.
The machine welds poorly. Polarity error (+/-). Check the polarity (+/-)
recommended on the electrode box.
