The Hot Start:
The Hot Start function is supposed to decrease faults in the start welding heat conductive materials
as for example aluminium. The Hot Start function is used with 1-MIG and pulse MIG welding. Time
is determined by SETUP parameters. The level of Hot Start can be changed by SETUP function.
The Hot Start level, Hot Start time, crater fill level and downslope time can be easily adjusted
using the ‘QUICK SETUP’ function:
1. First, press the SETUP button and then , while still pressing the SETUP button, press the
extra function button.
2. Adjust the Hot Start level.
3. Repeat step 1, upon which the display will show the next adjustable parameter.
Exit by pressing any button (except SETUP)
3.3.8. Use of gas test
If you press the gas test button, gas will begin to flow without any starting power source
or wire feed. Gas flow can be measured by using an external measuring device.
Cut off the gas flow by pressing the same button again, or the gun trigger. If the trigger
is not pressed again, the gas flow will end within 20 seconds.
The display will show “GAS” and the time.
3.3.9. Testing wire feed
The wire feed switch will start the wire feed motor without opening the gas valve. The
power source will start up, but without providing welding power. The wire feed range
will be 5m/min but can be adjusted as desired.
3.3.10. SETUP
Using the SETUP function, the user can change welding parameters which do not have their own
panel functions. These parameters can be set separately for 1-MIG and Pulse MIG. SETUP settings
are separate for each memory channel.
