replacement parts.
1.1
PLACEMENT
Unpack the machine and place it in an adequately venti-
lated area, dust-free if possible, taking care not to block
the air intake and outlet from the cooling slots.
CAUTION!
REDUCED AIR CIRCULATION causes overheat-
ing and could damage internal parts.
Keep at least 20 inches of free space around the machine.
Never place any filtering device over the air intake points

3 GENERAL DESCRIPTIONS
3.1 SPECIFICATIONS
This welder is used for welding soft steel, stainless steel
and aluminium.
3.2 EXPLANATION OF TECHNICAL SPECIFICATIONS
N°
Serial number, which must always be indicated
in any inquiry regarding the welding machine.
U
0
Secondary no-load voltage.
X
The duty cycle expresses the percentage of
10 minutes during which the welding machine
can run at a certain current without overheating.
Example: X = 60% at I2 = 100 A
This means that the machine can weld with a
current I2 = 100A for 6 out of 10 minutes, thus
60%.
I
2
Welding current
U
2
Secondary voltage with welding current I2
U
1
Rated power voltage.
1~60Hz
Single-phase 60-Hz power supply.
I
1
Current absorbed at the corresponding welding
current I
2
IP21
Degree of housing protection.
Grade one as the second digit means that this
device is not suitable for use outdoors in the rain.
