Arc Force can be found on our range of AC/DC Tig Welders both Digital and Analogue versions, it is also available on our Digital DC Tig Welders
This controls the arc during welding and will automatically adjust the voltage/amperage to maintain a stable arc, so it will maintain a good weld bead if if arc length changes during weld.
If the rod is pushed very close into the weld (tight arc length) the machine will compensate for the drop in welding volage by increasing it momentarily.
Lower setting is a more soft smooth arc, higher setting is a more aggressive arc (some call a more digging arc)
If you like ARC MMA welding with a tight arc (the stick is very close to workpiece) this will help stop the rod from sticking to the material.
As with many advanced settings this can be used in different ways.
- If you have a low setting of 30% - 50% for welding the you can keep a normal arc length and use the normal amperage for the job to hand.
2. If you like to keep a very tight arc, you can increase the arc force above 50% + and then reduce the main amperage, this will allow a tight arc length and prevent arc blow.
It is best to get some scrap metal and change the settings and write them down and compare each weld when finished, once you get it welding just ask you like it record these settings.
