The PrimeWeld CUT50DP 50-Amp 110v/220v Plasma Cutter provides your shop with inexpensive, powerful metal-cutting capabilities. It runs on either 110v or 220v outlets, providing amazing go-anywhere versatility. It comes with the accessories you need to unpack it and get to work. And at PrimeWeld, we back what we sell with unrivaled customer service.

50-Amp & 110v/220v Features

This 50-amp plasma cutter can go through 1/2-inch thick steel in a single pass when running on 240 volts. If you don’t have access to 220-volt power, no problem. The CUT50DP is also a rugged 110v plasma cutter that takes harsh shop conditions in stride. On 110 volts, it offers up to 40 amps with the ability to cut up to a 1/4-inch plate. This machine can get down to 10 amps output on either power source, low enough to cut auto body sheet metal.

ACCESSORIES

PrimeWeld includes a high-quality AG60P torch with this machine for industry-standard, easy-to-find consumable torch parts. The 13-foot torch hose on the CUT50DP 110v plasma cutter gives you room to work. We also ship our 50a plasma cutter with a set of replacement consumable parts.

At PrimeWeld, we build professional-quality machines that provide reliable service and great features at market-leading prices. The PrimeWeld CUT50DP 110v/220v Plasma Cutter equips your shop arsenal with metal cutting capabilities that save time and money while improving productivity and quality. It comes with a torch, grounding lead, air regulator, hoses, and extra torch consumable parts.

MOSFET INVERTER SYSTEM

The MOSFET inverter system makes for an incredibly light machine, weighing in at only 24 pounds. PrimeWeld incorporates a high-frequency, no-touch arc starting system for the CUT50DP 50 amp plasma cutter. Hold the torch just above the surface and pull the trigger. The torch starts without touching the surface, improving the lifespan of its consumable parts. This feature by itself adds value the competition can’t match at this price point.

How to Use

START CUTTING

Hold the torch vertical at the edge of the workpiece.

Pull the trigger to start the arc. The cutting arc will initial when the torch tip is close enough to the workpiece. Start cutting on the edge until the arc has cut completely through.

Then proceed with the cut.

HAND TORCH CUTTING TECHNIQUE

When cutting, make sure that sparks are exiting from the bottom of the workpiece.

If sparks are spraying up from the workpiece, you are moving the torch too fast, or you don’t have enough amps selected.

Hold the torch vertical and watch the arc as it cuts along the line.

PIERCING

Hold the torch at an angle to the workpiece. Pull the trigger to start the arc and slowly rotate it to an upright position.

When sparks are exiting from the bottom of the workpiece, the arc has pierced through the metal.

When the pierce is complete, proceed with cutting.

AMPERAGE

The standard rule of thumb is the thicker the material, the more amperage is required. On thick material, set the machine to full output and vary your travel speed. On thinner material, you need to turn down the amperage and change to a lower-amperage tip to maintain a narrow kerf. The kerf is the width of the cut material that is removed during cutting.

SPEED

Amperage and speed are critical to producing a good quality cut. The faster you move (especially on aluminum), the cleaner your cut will be. To determine if you’re going too fast or too slow, visually follow the arc that is coming from the bottom of the cut. The arc should exit the material at a slight angle away from the direction of travel. If it's going straight down, that means you’re going too slow, and you’ll have an unnecessary buildup of dross or slag. If you go too fast, it will start spraying back onto the surface of the material without cutting all the way through. Because the arc trails at an angle, at the end of a cut, slow your cutting speed and angle the torch in to cut through the last bit of metal.

DIRECTION

It is easier to pull the torch toward you than to push it. The plasma stream swirls as it exits the tip, biting one side and finishing off on the other, leaving a bevelled edge and a straight edge. The bevel cut effect is more noticeable on thicker material and needs to be taken into consideration before starting your cut as you want the straight side of the cut to be on the finished piece you keep.

TORCH TIP HEIGHT & POSITION

The distance and position of the plasma torch cutting tip has an effect on the quality of the cut and the extent of the bevel of the cut. The easiest way to reduce bevel is by cutting at the proper speed and height for the material and amperage that is being cut.

TIP SIZE & CONDITION

The top orifices focus the plasma stream to the workpiece. It is important to use the correct size tip for the amperage being used. For example, a tip with a 3/64” orifice is good for 0-40 amps whereas a 1/16” orifice is better for 40-80 amps. The low-amp tip has a smaller orifice which maintains a narrow plasma stream at lower settings for use on thin-gauge material. Using a 25-amp tip at a 60-amp setting will blow out and distort the tip orifice and require replacement. Conversely, using an 80-amp tip on the lower settings will not allow you to focus the plasma stream as well and creates a wide kerf. The condition of the tip orifice is critical to the quality of the cut result. A worn or damaged tip orifice will produce a distorted plasma stream resulting in a poor cut quality.

ELECTRODE CONDITION

A fixed gap is established between the electrode and the inside of the cutting tip. Electrons arc across the gap, ionizing and superheating the air, creating the plasma stream. The electrode contains an insert in the end made of highly conductive material called hafnium. This insert erodes with use and develops a pit in the end of the electrode. When the pit becomes too much, poor quality cuts will result and necessitate replacement of the electrode.

AIR PRESSURE & VOLUME

Air pressure, flow rate, and air quality are critical to the quality of the plasma cutting an consumable lifespan. The required air pressure and volume can vary from model to model and the manufacturer will provide the specs. The PrimeWeld CUT50DP air pressure is pre-set at 4.5 PSI and requires a flow rate of 6.0 CF/M.

The volume capacity of your compressor is important. If you have a small compressor with exactly the same l/min rating as the plasma cutter, then the compressor will run continuously when you are plasma cutting. A compressor with a l/min rating slightly higher than the plasma cutter would be more adequate. If you are doing a lot of cutting, cutting thick plate (same air consumption but slower cut speeds = longer cut time), then choose a compressor at 1.5 to 2 times the plasma system requirement.
