Plug Installation
Do to the wide variety of 240V plug types, the Hot
Max AC300 is shipped with out a plug. The user will
have to purchase and install a plug. These welders re-
quire a 240V 50 Amp plug.
Please refer to the instructions packaged with the plug
for proper installation. The unit is shipped with a 6’
three conductor power cord with a blue and red hot
conductor and a yellow and green (ground) conductor.
Electrode & Ground Cable Connection
AC300
1. Slide a 10mm lock washer and 10mm flat washer
onto the 10mm x 16mm bolt and attach the ground
clamp cable to the negative cable terminal on the
right side of the welder (as you face the welder).
2. Slide a 10mm lock washer and 10mm flat washer
onto a 10mm x 16mm bolt and attach the electrode
cable to the desired positive cable terminal on the
left side of the welder (as you face the welder).
The positive cable terminal selection is determined
by the power output required for the welding oper-
ation being performed. The lower terminal is for
operating ranges of 50 –210 Amps and the upper
terminal is for operating ranges of 55 –250 Amps.
Note: Very few operations require amperage as
low as 35 , therefore, it is recommended the
electrode be connected to the upper terminal.
