SAFETY CONSIDERATIONS ELECTRIC ARC WELDING EQUIPMENT CAUTION : READ BEFORE ATTEMPTING INSTALLATION, OPERATION OR MAINTENANCE OF THIS EQUIPMENT 1-1 INTRODUCTION This equipment is intended for ultimate application by commercial/industrial users and for operation by persons trained and experienced in the use and maintenance of welding equipment. Operation should not be undertaken without adequate training in the use of such equipment.
general rules cover many of the most common situations. 1. Pressure Regulators Regulator relief valve is designed to protect only the regulator from overpressure; it is not intended to protect any downstream equipment. Provide such protection with one or more relief devices. Never connect a regulator to a cylinder containing gas other than that for which the regulator was designed. Remove faulty regulator from service immediately for repair (first close cylinder valve).
acute sunburn; those from gas-shielded arcs are more severe and painful. DON’T GET BURNED; COMPLY WITH PRECAUTIONS. 1. Protective Clothing Wear long-sleeve clothing in addition to gloves, hat, and shoes. As necessary, use additional protective clothing such as leather jacket or sleeves, flameproof apron, and fire-resistant leggings. Avoid outer garments of untreated cotton. Bare skin protection. Wear dark, substantial clothing.

Torch Lead Connections Power Cable - Air Cooled A #2 AWG power cable is used on the Python® air cooled torch. The torch end is threaded into the torch body. The power cable fitting connects to the power block in the Cobramatic® wire feed cabinet. Power Cable - Water Cooled Python® water cooled torch utilizes a power/water cable with a #4 AWG cable inside a 5/8” (16MM) diameter hose.
Trigger Sensitivity The amount of trigger level travel can be shortened for a quicker or more responsive action. A more sensitive trigger lever is produced by reducing the gap between the trigger lever and the micro switch lever. By turning-in the trigger sensitivity adjustment screw, it closed the gap between the trigger lever and the micro switch lever. This well enable the operator to increase the sensitivity of the trigger lever.
3. Once the drive roll is loose, continue to spin drive roll in the clockwise direction to remove the drive roll from the torch. 4. Install a new drive roll on the left-hand threaded shaft. The drive roll will self-tighten when it is feeding wire. Idler Roll Installation and Removal (Reference Figure 3) 1. Using a slot type screwdriver, loosen idler screw, taking care not to lose lock washer under idler roll. 2.

Section E Troubleshooting Trouble No wire feed at torch, feeder not operating, i.e. no slave motor or brake solenoid. No wire feed at torch, feeder operating properly. Wire feeds, but welding wire is not energized. Wire feeds erratically. Wire feeds one speed only. Wire walks out of drive rolls. Cause Input power fuse in feeder/control box blown Remedy Replace fuse. Micro-switch defective/not Replace switch. Check being activated switch for operation.
Troubleshooting Guide Regardless of which torch or feeder used, all MK Products’ push-pull guns operate on the same principle. The slave motor in the feeder runs at a fast,constant speed, but has very low torque. It is always trying to feed more wire than the torch motor wants, and when the motor gets all it wants, it slows the slave motor, preventing a bird’s nest. Because of the low torque produced by the slave motor, a brake system is used to prevent wire overrun rather than tension.
