Start Up
Turning On
• Turn ON the general switch (A) located in the back side
of the welder.
• When the ON light is on (B) the internal fan will start
running.
Adjustments
• As a general rule, low current requires feeding the micro
wire in low speed. If increasing the work current is
necessary, increase the micro wire speed as well.
• To set up the work current use the tension control (C).
• To configure the micro wire outlet speed, use the micro
wire speed control (D).
• Remember to make tests in scrap material with the same characteristics as the final material to determine the right
configuration for the job. Aside from current and micro wire speed there are other factors intervening in the welding
performance, like the wire diameter and characteristics, the distance between the nozzle and the work material, the torch
angle and the amount of gas delivered.
Equivalence table (voltage and current selector)
Use this control to select the appropriate voltage or current for the job to be performed, from a minimum value (position
1) to a maximum value (position 10).
