When the button is pressed and released again, the arc will be extinguished and gas will flow out. When the gun button is pressed, gas pre-flows, then strikes the arc and starts welding with the starting current HotI. After the HOTt time has elapsed, the welding current value will change to the set value.

    7. PARAMETER SETTINGS 7.1 Method of MMA and PULSE MMA After selecting the MMA or PULSE MMA method, it is possible to adjust the parameters according to the table below. The welding current can be adjusted with the adjustment knob immediately after switching the machine on or switching over welding methods.
  • Page 19 7.3 SYN MIG, PULSE, D-PULSE and SPL MIG method During MIG welding, the device can operate in synergic (SYN MIG, PULSE, DPULSE) and manual (SPL MIG) modes. The synergic mode allows less experienced users to choose welding parameters. In this mode, the device automatically selects the welding current and wire feed speed depending on the type of material to be welded and the diameter of the electrode wire.
  • Page 20 Pulse width The width of the pulse is the duration of the pulse, it allows you to adjust the depth of penetration. Increasing the width increases the penetration depth, reducing the amount of heat introduced into the material, reducing the risk of burning through thinner sheets or smaller components.
