· When the welding torch is adjusted slow down, the welding depth will increase and the weld-
ing line will increase.
· A good welding line needs to comprehensively adjust the above parameters. For this, you may
refer to the welding specifications in Tables 2~8.

5-3. The constant voltage output static characteristic curve of the machine is as
shown in Figure 7 below.
Constant Voltage Output Characteristics of SW-1250
Note: M-AM-BM-C is the output static characteristic curve while N-C load curve.
· You may adjust the welding voltage with the voltage adjustment knob of the control box of
the welding tractor, i.e. adjust the distance between the points A, B and C on the output char-
acteristic curve and the horizontal axis.
· M-A, M-B and M-C selections are the constant voltage output characteristic sections of the
machine and the adjustment ranges from the min. voltage to the rated welding voltage of the
machine.
