Comments |
| Steel, mild |
To 6” plate, 12” round |
10”-12” per 18” rod, 45 sec |
Easy cut, pierce, gouge. |
| Steel, stainless |
To 4” plate, 12” round |
8”-10” per 18” rod, 45 sec |
Rougher edge than mild steel, slower cutting rate. |
| Steel, wear plate |
To 6” plate |
10”-13” per 18” rod, 45 sec |
Some wear plate cuts faster than mild steel due to hardening alloys being more combustible. |
| Cast iron |
To 4” thick |
4”-6” per 18” rod, 45 sec |
Produces much yellow/brown smoke, faster cutting rate if welding power (100 amps) is used with torch negative (-). |
| Aluminum |
To 6” thick, 12” round |
8”-10” per 18” rod, 45 sec |
Use only long rod and/or PC/XT rod extender. Use full head covering and leathers. Much sparking and spalling.
Aluminum is very volatile. Thin aluminum cuts very quickly. |
| Titanium |
To 6”+ thick, 12”+ round |
12”-15” per 18” rod, 45 sec |
Very easy to cut, somewhat volatile but much more controlled than aluminum. A good metal for this process. |
| Concrete |
Holes to 8” depth |
3” hole per 18” rod |
Melt holes only. Prefer mechanical method with Prime Cut to get the reinforcement bar. Not practical for cutting. Melt series of holes to weaken concrete, then fracture. |
| Inconel, monel, nickel, high chrome, bronze |
Treat as stainless. Good performance on these metals. |
