SECTION 3: INSTALLATION 3.04 Setting Up Machine Torch WARNING 3.01 Introduction This Section describes installation of the Liquid Cooled Maximizer 300 Torch. These instructions apply to the Torch and Leads Assemblies only; installation procedures for the Power Supply, Options, and Accessories are given in Manuals specifically provided for those units. The complete installation consists of: 1. Site Selection Disconnect primary power at the source before disassembling the torch or torch leads.
7. Place the hose clamp over the shield and hub. Tighten the hose clamp to secure the shielding braid to the hub. 3.05 Connecting Torch NOTE WARNING Make sure that the shielding braid is pulled back as far as possible from the bulkhead connections. Leave any extra shielding braid between the hose clamp and the front panel area. Disconnect primary power at the source before disassembling the torch or torch leads. The Torch Leads connect directly to a bulkhead inside the Power Supply.
2. Nitrogen (N2) Plasma 2. Carbon Dioxide (CO2) Secondary • Provides better cut quality on nonferrous materials such as stainless steel and aluminum. • CO2 secondary is used with nitrogen or Ar/H2 plasma. • Can be used in place of air plasma with air secondary or carbon dioxide (CO2). • Provides good cooling and maximizes torch parts life. • Provides much better parts life than air. • Provides good cut quality on ferrous or nonferrous material. • A good clean welding grade nitrogen should be used.
3.07 Gas Connection A. Connection Connect the gases to the Power Supply as described in the Power Supply Operating Manual (0-2251) supplied with the Power Supply. CAUTION Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting performance and rapid electrode wear. B.
SECTION 4: OPERATION D. Gas Supplies Select desired gas supplies. Make sure gas sources meet requirements (refer to Section 2.03, Specifications & Design Features). Check connections and turn gas supplies on. 4.01 Introduction E. Purge System This Section provides a description of the Liquid Cooled Model Maximizer 300 Torch Assembly followed by operating procedures. On the Power Supply place the ON/OFF switch to the ON position.
4.04 Torch Parts Selection Torch Head Depending on the type of operation to be done determines the torch parts to be used. Electrode Torch parts: Shield Cup Body, End Cap, Tip, Electrode, Gas Distributor Tip Gas Distributor Type of operation: Shield Cup Body Standoff cutting or gouging Refer to Section 6.04, Torch Consumables, for the various torch parts. End Cap Art # A-02207 Figure 4-2 Liquid Cooled Torch Parts CAUTION 2. Using the multi-purpose wrench (5/8 inch slot) remove the tip.
E. Bottom Dross Build-up 4.05 Cut Quality Molten material which is not blown out of the cut area and re-solidifies on the plate. Excessive dross may require secondary clean-up operations after cutting. NOTE Cut quality depends heavily on set-up and parameters such as torch standoff, alignment with the workpiece, cutting speed, gas pressures, and operator ability. Cut quality requirements differ depending on the application.
Typical Cut Quality on Various Materials Type of Material Type of Gases Material Thickness Carbon Steel Stainless Aluminum Air Plasma and Air Secondary Gauge to 2 inches (Gauge to 50.8 mm) Good Good Good Gauge to 1/4 inch (Gauge to 6.4 mm) NR Good Good 1/4 to 1 inch (6.4 to 25.4 mm) NR Excellent Good - Excellent 1/4 to 1/2 inch (6.4 to 12.7 mm) NR NR Excellent 1/2 to 2 inches (12.7 to 50.8 mm) NR Excellent Excellent Gauge to 3/8 inch (Gauge to 9.
B. Torch Standoff ten be wiped off with a welding glove. "Slow speed dross" is normally present on the bottom edge of the plate. It can vary from a light to heavy bead, but does not adhere tightly to the cut edge, and can be easily scraped off. "High speed dross" usually forms a narrow bead along the bottom of the cut edge and is very difficult to remove. When cutting a troublesome steel, it is sometimes useful to reduce the cutting speed to produce "slow speed dross".
4. With the pilot arc on, the main cutting arc will be established when the torch is brought within 1/8 - 3/8 in (3 - 10 mm) of the workpiece. If the cutting arc is interrupted and the torch is still activated, as when cutting expanded metal, the pilot arc will automatically restart. Deactivating the torch will shut off either the pilot or main arc, depending on the mode of operation. Shown with Rack and Pinion Mounting Assembly NOTE Refer to Auto-Restart Options in the Power Supply Operating Manual.
C. Piercing With Machine Torch 4.08 Recommended Cutting Speeds To pierce with a machine torch, the arc should be started with the torch positioned as high as possible above the plate while allowing the arc to transfer and pierce. This standoff helps avoid having molten metal blow back onto the front end of the torch. Cutting speed depends on material, thickness, and the operator’s ability to accurately follow the desired cut line.
Characteristics of Recommended Gases for Plasma Arc Gouging Type of Gas Type of Material Plasma Secondary Carbon Steel Stainless Steel Aluminum Air Air Excellent Good Fair Nitrogen Air Good Good Fair Nitrogen CO2 Good Good Good Ar/H2 Nitrogen Good Excellent (Over 3/4 in) Excellent Ar/H2 Argon Good Excellent Excellent B.
The inside of the torch should be cleaned with electrical contact cleaner using a cotton swab or soft wet rag. In severe cases, the torch can be removed from the leads (refer to Section 5.06, Servicing Machine Torch Components) and cleaned more thoroughly by pouring electrical contact cleaner into the torch and blowing it through with compressed air. SECTION 5: SERVICE 5.01 Introduction This Section describes basic maintenance procedures performable by operating personnel.
g. Output current too high NOTE DO NOT use other lubricants or grease, they may not be designed to operate within high temperatures or may contain “unknown elements” that may react with the atmosphere. This reaction can leave contaminants inside the torch. Either of these conditions can lead to inconsistent performance or poor parts life. h. Torch tip contacting workpiece i.
