Welding Operations - ESAB ARC250i Instruction Manual

WELDING OPERATION
High voltage danger from power source! Consult a qualified electrician for
proper installation of receptacle at the power source. This welder must be
grounded while in use to protect the operator from electrical shock. If you are
not sure if your outlet is properly grounded, have it checked by a qualified
electrician. Do not cut off the grounding wire or alter the plug in any way and do
not use any adapter between the welder's power cord and the power source
receptacle. Make sure the POWER switch is OFF then connect your welder's
power cord to a properly grounded 230 VAC, 50 HZ, single phase, 50 amp power
source.

Once the installation of the equipment is completed, connect the work Cable to
the negative output terminal and the cable end of the electrode holder to the
Positive output terminal. These cable connections should be tightened properly
to avoid electrical heating due to loose connections. Put the main Switch box in
'ON'. Turn on "Power ON/OFF switch" on the rear panel. The Display on the
panel of the Power Source will glow and the fan will start rotating. Now the
equipment is ready. Connect an Electrode with the Electrode Holder. The
welding current can be controlled by the current control potentiometer mounted
on the front panel of the Power.
Welding Current Adjustment
Put the MMA/ TIG switch to 'MMA' mode. Now set the DC output current as
required with the help of the current control potentiometer and ignite an
experimental Arc. For the fine-tuning of the required current, set the parameters
using the Ammeter mounted on the front panel of the power source.
