With the three position switch (1) you can set the MIG welding gun to two-sequence (2T) or
four-sequence (4T) mode with GasGuard feature on.
If you are using self-shielded flux-cored filler wire (gasless wire), you must select the upmost
switch position. This position provides 2T operation with GasGuard feature disabled, allowing
welding without shielding gas.

1. Press the gun trigger down to start welding.
2. Release the gun trigger to stop welding.
to use the welding gun in 4t operating mode:
1. Press the gun trigger down to start the flow of the shielding gas.
2. Release the trigger to start welding.
3. Press the trigger down again to stop the arc. The shielding gas continues to flow.
4. Release the switch again to stop the flow of the shielding gas.
