Lotos LTP5600CD
#8 in Over 45 AFull review
For mobile repair and field cutting where no air compressor is on hand. Shop users who already own a compressor get more for the money from a cutter without one.

3.6/5
For a hobby or farm shop that wants a cheap dual voltage cutter with a pilot arc for 1/2 in steel and below. Look elsewhere if it will run on a CNC table.

Pros
- Pilot arc for under $400, so painted and rusty metal cut without touching the tip
- Cuts 1/2 in steel on a 240 V outlet and 1/4 in on a household outlet
- Light at 24 lb, easy to carry to the job
Cons
- High frequency start can upset nearby electronics and rules out most CNC tables
- Duty cycle is rated at 25 C, so expect less in a hot shop
- Three year warranty, shorter than some rivals

For a home shop that wants one dual voltage 60 A cutter for hand work now and a CNC table later. Good value if three years of cover is enough.
