OPERATE THE SAFETY TRIGGER 

The hand torches are equipped with a safety trigger to prevent accidental firings. 

 

 

Hand torch cutting suggestions

 

 

Drag the torch tip lightly along the work piece to maintain a steady cut. 

 

While cutting, make sure that sparks exit from the bottom of the work piece. The sparks should 
lag slightly behind the torch as you cut (15° — 30° angle from vertical). 

 

If sparks spray up from the work piece, move the torch more slowly, or set the output current 
higher. 

 

With either the 75-degree or 15-degree hand torch, hold the torch nozzle perpendicular to the 
work piece so that the nozzle is at a 90° angle to the cutting surface. Observe the cutting arc 
as the torch cuts.

 

 

 

 

If you fire the torch unnecessarily, you will shorten the life of the nozzle and electrode. 

 

Pulling, or dragging, the torch along the cut is easier than pushing it.

 

 

 

For straight-line cuts, use a straight edge as a guide. To cut circles, use a template or a 
radius cutter attachment (a circle cutting guide).
