TIG welding machine and plasma cutting machine

1. Invertig-160 DC has small size and large output. Since it can operate at 110 or 220 volts, it is very suitable for home use or from work to work. The power cord is 15 feet long and requires an end cap, depending on your settings (you choose a 20-30 amp power outlet). The foot pedal and the flashlight each have 25-foot-long leads. Invertig-160 DC also comes with a flow meter with a 6-foot hose for shielding gas (argon). You can also get a starter kit, which includes tungsten wire, chuck, chuck body, and alumina cup for the torch. There are four different sizes and the price is about $50.

2. There are cooling fan and voltage switch (110 or 220V) on the back of Invertig-160 DC, as well as protective gas port.

3. Before starting, we first need to connect the protective gas (argon) hose from the bottle to the back of the Invertig-160.

4. The hose comes with a flow meter. The flow meter provides you with more accurate gas measurement than traditional gas regulators. Once connected to the bottle, only 15-20 cubic feet per hour (CFH) of argon flow is required. Make adjustments here (arrows). (Do not use tape-the thread is not sealed-the accessories are OK)

5. On the front of Invertig-160 DC, we need to connect the flashlight to the gas line, foot pedal and ground wire. There are twist locks on the ends of the torch and ground cable. You can see (arrows) that you need to align the tabs to fit the device, and then twist the cable to lock it in place.

6. (#1) This column is the negative output socket of the TIG welding torch. On Invertig-160 DC, all TIG work is performed with positive polarity, the cutting torch is negative and the positive is grounded. If rod welding then this will be a different setting, we can discuss it later, now we are setting up TIG welding. (#2) This is the pin trigger connection of the TIG welding gun with built-in switch function. We use the foot pedal as the switch, so it is not used at this time. (#3) This is the installation position of the gas (argon) line from the welding gun, which is controlled by the solenoid valve inside the welding machine. (#4) This is the installation position of the foot pedal (current control), which is also a push and twist lock installation. (#5) This is the positive output socket. When the TIG is soldered, this is where the ground cable is connected. Once again, all TIG work is done with positive polarity, with the torch being the negative pole and the positive pole being grounded.

7. This is a screenshot of the control panel, starting with three indicator lights, power supply, welding current and thermal switch (A). This is the ramp down or point time (B). This is the final current knob, which can be adjusted from 10% to 90% of the base current (C). This is the post gas flow adjustment (D). This is the welding mode switch; there are five settings, four for TIG (material based) and one for bar welding (E). This is the current intensity adjustment knob (F). This is a remote/local switch, used to operate a foot pedal or a flashlight to control the current intensity (G). This is the Lift Arc/HF switch. You can choose to make tungsten contact with the welding arc or use the pedal (H) to trigger the arc. If you choose, you can use and adjust pulse TIG welding by turning this knob, or this can be done with the foot pedal (I) in the closed position.

8. This is a 17 series flashlight. This is an air-cooled cutting torch, which consists of an alumina nozzle (A), a gas lens chuck body (B), a chuck (C) and a tungsten rod (D).

9&10. Choose the tungsten diameter according to the thickness of the material to be welded. 1/16 inch tungsten is suitable for metal plates up to about 1/8 inch. Then select the matching 1/16-inch chuck and 1/16-inch chuck body. Then install the alumina cup of the correct size to guide the argon shielding gas around the weld. If you are welding 1/8 inch to 1/4 inch material, you will want to use 3/32 inch tungsten. The type of tungsten is specified by the color of the tip. We got 2% thorium tungsten, which has a red tip for welding steel and a green tip for welding aluminum.

11. Once we are set up and ready to solder, Invertig-160 DC is easy to use and can be adjusted as we proceed. The flashlight is very suitable for our hands. It is easy to pick up and reduce the flow rate by controlling Arc with a foot pedal.

12. In addition, if you need, HTP provides a DVD ($60), which contains more than 70 minutes on how to perform TIG welding and set up the welding machine, different arc starting, tungsten types, machine control and most important welding errors Information.

13. This is the HTP Micro Cut 301 plasma cutting machine. We all know how difficult it is to cut a clean line on a thick fender or sheet metal with a grinder, so if you are a manufacturer, this compact device is a great addition to your garage. The device requires 220 volt power and compressed air.

14. First, we need to install a bracket for the pressure gauge with regulator. The bracket on the back of the cutting machine has two small cross-head screws. Then we connect the air hose to the quick connector (arrow) on the regulator.

15. The following is the appearance of the regulator when the air accessory is installed on the cutting machine. You can also find the power switch on the back.

16. On the front of the plasma cutting machine, you will find an indicator light and a cutting power adjustment knob.

17. The torch has a safety trigger switch cover, a 13-foot power cord, and a 9-foot ground wire (not shown).

18. This is a torch component failure, starting with the handle, then the swirl ring (A), then the electrode (B), the cutting tip (C), and finally the gas diffuser (D). In addition, you can get extended electrodes and cutting heads suitable for different cutting methods.

19. After turning on the power and connecting to the air compressor, we set the cutting power to the size of the sheet metal part we are processing. Then we flip the switch and press the trigger, our cutting is smooth and fast. Whether we are cutting flat or curved sheet metal parts, it is easy to get used to how to move the torch over the cutting area. 301 can easily cut steel, stainless steel, aluminum or any other conductive materials.

Nowadays, everyone is looking for a way to save a little money, from oil changes to small repairs, they repair the bicycle by themselves. One thing that seems to be on the rise is that more and more people are doing their own fab jobs. However, if you have to find a store to do all the welding for you, this can become expensive. Therefore, if you are looking for a home TIG welding device, but don't want to take a second mortgage on your house, then we have found what you are looking for. HTP America Inc. has a full range of welding machines and plasma cutting machines, which is ideal for home builders and full-service shops.

After talking to the HTP team and letting them know the needs of home welders, they recommended us the Invertig 160DC ($1,299, please consult your local dealer), a full-featured DC TIG welder for welding steel. Using DC argon arc welding machine, you can weld steel, stainless steel, 4130 pipe, basically all weldable metals except aluminum and magnesium. If you want to weld aluminum and magnesium, you need an AC/DC TIG welder. 160DC has a high-frequency arc starting function, so you don't need to touch the tungsten to the workpiece to start the arc. It also has a remote current control controlled by a foot pedal or a fingertip mounted on the welding gun, allowing you to change the current while welding, allowing you to fully control the weld pool. It also has a pulse function to minimize heat input in thin materials.

This compact device weighs 32 pounds and measures only 16 inches long x 12 1/2 inches high x 8 inches wide. It can be plugged in anywhere because it works at 110 or 220 volts. If you choose to add an optional electrode holder (accessory required), Invertig 160DC can also be used as a rod welder.

In addition, if you do your own fab work, you may find yourself looking for a way to cut the sheet metal before soldering. Therefore, we also studied the MicroCut 301 plasma cutting machine. MicroCut 301 cuts 5/16 inch steel at a speed of 12 inches per minute and can cut 3/8 inch steel. It requires a 16 amp 220 volt circuit and a cutting current setting from 5 amps to 25 amps to save energy. The MicroCut 301 device weighs 14 pounds and is light enough to be moved wherever you need it. MicroCut 301 comes with a 90-day money-back guarantee and a one-year full warranty, with a retail price of US$799.
