Hypertherm torches are all designed for drag cutting on the plate. Systems above 30 amps use Hypertherms patented shield technology....so there is no effect on consumable life when drag cutting...no double arcing or sticking to the plate.
Simply pierce, then lower the torch to drag on the plate....you can guide the edge of the torch on a pattern or straightedge made from metal, plywood or cardboard if needed.
Hypertherm systems are certainly more expensive than the low cost imports...but are designed for reliability, ease of use, and provide for lower operating costs (better cut quality, dramatically longer consumable life) that result in a lower cost of ownership. Did I mention that they are made in the USA (Hanover, NH) by employee owners of the company?
I had a job two weeks ago dismantling a 60' long steel mezzanine catwalk in an industrial building. I used a Hypertherm Powermax45....and cut up over 15,000 pounds of steel (3/16" treadplate, 1/2" and 1/4" thick I beams, bar joists, 3 x 3 x .375 tubing, 3/16" steel stairtreads, 1/2" gusset plates) into parts smaller than 2' x 5' (carryable by one man). The job took me three 8 hour days, the Powermax45 had a used nozzle when I started, the same nozzle was in it after the job was done. All cuts were drag cuts right on the plate. There is not a chance that an oxy-fuel torch would have cut that much steel as fast or as cheap! I have a few pics if anyone is interested...
I use the same plasma on my cnc machine in my home shop...
